    Tablets Ubuntu

    Ubuntu-Powered Tablets Coming From Startup MJ Technology

    MJ Technology LLC announced the availability of its anticipated Ubuntu tablet line, revealing the specifications of its products and offering them for preorder on its upcoming website. We first reported on MJ Technology back in December and were excited at the prospect of an OEM bringing Canonical's Ubuntu Touch operating system to a mobile device. It seems the dream is finally a reality, and Ubuntu users can now look forward to a tablet with some serious performance sporting the OS.
    MJ Technology advertises these tablets with an Intel 2.4 GHz quad core processor inside, but aren't giving specific details on which Intel chips it's actually using. It could be that these specifications are not finalized yet, but with options for mobile quad core Intel processors limited, the tablets are likely loaded with the Bay Trail or newer Cherry Trail architectures. Either way, any recently available 2.4 GHz quad core Intel processor is plenty of performance for a tablet, and enough to forgive the ambiguity. With 4 GB of DDR3 RAM, the devices appear to offer ample horsepower for any task you could expect to perform on a tablet.
    Internal storage for these devices is 64 GB by default, but there's a 128 GB option, too. The microSD slot can support up to 128 GB, so in theory you could have 256 GB of total storage if you combined the 128 GB internal storage and a 128 GB microSD card.
    Additional connectivity includes one USB 2.0 port, one USB 3.0 port, one micro USB port for charging devices, and external access to a mini PCI-Express slot. Normally, you wouldn't see a mini PCI-Express port on a tablet, and laptops generally don't provide easy access to it. It can be used to attach USB, wireless or video cards, but good luck finding one that will load Ubuntu drivers. The mini PCI-Express port can also be used for connecting diagnostic equipment via a data cable. Overall, the Ubuntu tablets appear quite versatile.
    The two tablets come in 8.9- and 10.1-inch sizes, with both sporting 1920 x 1200 resolution 10-point multi-touch IPS touchscreens. A micro HDMI output provides more flexibility with display options, and there are onboard 8MP and 13MP cameras on the front and back of the device, respectively. Wireless access is provided by dual band 2.4/5 GHz 802.11 a/b/g/n Wi-Fi. The tablets also have Bluetooth 4.0, allowing users to connect an optional keyboard or other devices.
    The 8.9-inch model has a 7,500 mAh battery designed for seven or eight hours of working time. The larger 10.1-inch version has a slightly more powerful 8,500 mAh battery, offering eight to nine hours of juice under standard operation.
    MJ Technology is releasing the tablets with the latest version of Ubuntu Desktop with Unity, but will offer Ubuntu Touch in October once a stable version is released by Canonical. Users who choose to preorder can opt to stay with the loaded desktop version of Ubuntu or download the Ubuntu Touch OS once it is available.
    These tablets seem more like powerful mini-laptops or Chromebooks considering their specs, and the MSRP suggests the Ubuntu-powered devices will compete directly with those bulkier alternatives. The 8.9-inch model is estimated to launch at $349, and the 10.1-inch model will be $399. You can preorder these Ubuntu tablets soon at MJ Technology's official website, and the company expects full retail availability some time in January.

    Canonical Impresses With Ubuntu Core And Low-Power Mobile Devices

    We saw three surprising things at Canonical’s booth at Mobile World Congress 2016, and each has to do with conversion. By "conversion," I mean a mobile device equipped with Ubuntu Core – a shared code base that enables apps to run on mobile and desktop, whether designed for touch or mouse and keyboard input – that can connect to an external monitor and see the apps optimized for the larger display.
    If that sounds a lot like Microsoft’s Universal Apps and Continuum, that is because it’s the same concept. But as Microsoft is struggling to finish and polish its software, Canonical went ahead and did it better.

    Canonical's MWC Surprises: A Tablet-As-PC, An Old Smartphone-As-PC, And a High-End Disappointment
    A Midrange Tablet Impresses

    Even after an impressive web demo ahead of the show wherein Canonical demonstrated a tablet running a PC-like experience with a mouse and keyboard, I had little optimism that the BQ Aquaris M10 Ubuntu Edition tablet would be able to multitask as Canonical proclaimed it could. The specs just seemed too middling: a MediaTek quad-core MT8163A (up to 1.5 GHz) and 2 GB of RAM?
    I was wrong.
    Richard Collins, Ubuntu Mobile Product Manager for Canonical, walked me through a demo of the tablet in action. It had a mouse and keyboard connected via Bluetooth, and he swiftly opened up a number of applications. In the video, you can see that he has a web browser running in addition to a music player, contacts, email and more.
    Touch Mode
    He started off showing me touch mode, wherein you can swipe in from the left to show a list of app icons. When you tap to open an app, you can then do a three-finger drag to stick it on the left side of the screen, so you have one larger window and one smaller window -- what’s called the “Side Stage.” (This, versus the larger “Main Stage” window of the tablet.) You can interact with both open apps at once.
    If you want a Side Stage app to appear on the Main Stage, you can just three-finger drag it to the larger area.
    When you slide in from the right, you can see all your open apps in tiles, and you can tap any to bring them to the forefront. Within the Side Stage, you can actually swipe from the right to toggle through your open apps, too.
    Desktop Mode
    Then he brought the mouse and keyboard into the conversation. You can, by the way, use the touch gestures even while the mouse and keyboard are connected. To engage the mouse-and-keyboard-friendly mode, you bring up a panel and toggle on "Desktop Mode." In Desktop Mode, you can see all your open apps in windows, just like on any PC desktop. All the same apps you had running in Touch Mode are still open; they just automatically optimize themselves for the Desktop Mode. This change happens instantly -- so quickly that if you blink, you’ll miss it.
    Just like on a regular PC, you can click and drag the windows around as you see fit. And you still get the app icon list on the left side of the display -- you just mouse over, and it will pop out.
    Collins opened LibreOffice as well as a spreadsheet. It took maybe a beat longer to open than such an application would on a regular PC. At this point, he had LibreOffice, Scopes, System Settings, Music, the web browser, Contacts and xChat GNOME all running.
    After I shut the camera off, by the way, I dug in there to see if I could choke the system. I hit “play” on the music app, opened up the camera so the “live view” was up, loaded a couple of web pages, and pulled up a spreadsheet and started typing. There was simply no lag. In terms of responsiveness, it felt as if I was on my regular laptop. The web pages even loaded more quickly on the tablet than they sometimes do on my laptop. I clicked back and forth between open applications. Smooth as mantequilla.
    The only limitation I saw at this point is that there’s no support for a dual-display mode. Therefore, you can use the tablet like a PC, or connect the tablet to an external display and use it as a PC, but you can’t do both. Canonical told me that this is a limitation of the chipset, but that “in theory, with the right hardware, [dual display] will be possible in future.”
    Just Some Old Smartphone Acting Like A PC

    I was sufficiently impressed by the Aquaris M10 Ubuntu Edition tablet demo’s multitasking performance, but Collins had another surprise in store when we switched to the smartphone-as-PC demo.
    Thanks to Ubuntu Core, you can connect a smartphone to an external monitor, and the phone’s open applications will show up as windowed, desktop-looking apps.
    As with the tablet, you can’t get a dual-screen experience. However, Canonical cleverly found a way to use the smartphone’s touch display as an input device. The phone’s display is off, but in the video (above), you can see that you can use it to move the mouse cursor around just as you would on any laptop touchpad, and you can perform taps and a two-finger scroll. (When connected to an external display, the tablet offers the same.) Connect yourself a keyboard, and you’re all set with a hybrid laptop/desktop input experience and a PC-like environment on your monitor.
    However, it’s not as fluid as the tablet experience. There’s a small amount of mouse input lag, for example, and the apps didn’t seem to respond quite as readily as one would like. That would be more disappointing if the attached smartphone powering the experience was a high-end device, but effectively, they were using just some old smartphone. It was, in fact, a Nexus 4--a phone so old that you can’t even buy it anymore.
    I pressed Collins on the minimum required specs for this experience, and I seemed to have stumped him, as he didn’t have a ready answer. But then he made this point: Canonical hasn’t bothered to define minimum requirements because there are so few phones available that can’t run it.
    All a handset really needs, Collins said, is 2 GB of RAM. The rest is gravy. The Nexus 4 was used just as a prototype, and Collins told me that another handset was coming this year that should fully support this experience. Around that time, a dual-display feature should become available, as well.
    “Odd,” might be your next thought, “Why not just use that recently-announced, high-end Meizu Pro 5 Ubuntu Edition smartphone?”
    A High-End But Hamstrung Handset

    That thought would make sense--the Meizu Pro 5 is a fairly powerful device, and it has a USB Type-C port that should make it ideal for pumping its contents to an external display. But there’s one great big problem: Inexplicably, the phone doesn’t support video out through the Type-C port.

    Regarding this oversight, Collins said, “This is a chipset dependency and requires the chipset supplier to enable video support for the USB Type-C component on the Board Support Package. We expect chipset manufacturers to fully enable USB-C type functionality for future boards.”
    He continued, “There are alternative technologies we are evaluating and expect products in the near future.” One of these potential solutions, he said, is Wi-Fi Direct, which could potentially turn any Ubuntu phone into a “convergence” phone. For now, though, the Pro 5 is “just” an Ubuntu phone.

    Basically an iPhone 6 clone in terms of design, the Pro 5 has a Samsung Exynos 7420 SoC with a Mali T760 GPU, 3 GB or 4 GB of LPDDR4 RAM, 32 GB or 64 GB of UFS 2.0 storage, and a rear 21.16MP camera (with a Sony IMX230 sensor).
    Being an Ubuntu phone, it uses Scopes; the UI design is intended to keep people in the experience as opposed to bumping them off to web-based “apps,” and to that end, many apps have a unified Ubuntu look, like the SoundCloud app in the video.
    Enabling Convergence

    Collins said that devs can enable this Ubuntu-on-any-screen capability fairly easily, using Canonical’s SDK. “Our SDK has UI components, which when used to create applications to run on Ubuntu devices will allow the app to dynamically change so that it can be used for touch as well as mouse control and input,” he stated. “This is a both a design and a technical solution we have introduced to allow any app to be relevant for convergence.”
    So, yes, devs have to go into their app’s code and add a few lines, and that means currently not all apps can switch from touch mode to desktop mode as smoothly as the ones I saw demoed. Surely, that will lead to a certain amount of consternation for users, but as demand increases, the number of enabled apps should follow quickly.
    What Canonical is doing here is all the more impressive because of the issues Microsoft appears to be having in implementing its own convergence experience for mobile devices using Windows 10 and Continuum. Windows 10 for phones is still not finished, and as Collins noted, “The mobile version [of Windows 10] has the ability to display certain apps to a desktop, but still remains a mobile OS at its core.”
    He added, “Continuum is therefore a solution for the Win 10 mobile OS variant which only works for certain apps. It is a feature of their mobile OS and is not therefore based on true OS convergence in the same way as Ubuntu.”
    Canonical itself still has some work to do. More apps need to get the convergence treatment, and we need to see more available devices, Further, getting video-out capabilities on these higher-end Ubuntu phones is crucial--there's no two ways about that--and adding dual-display support for both phones and tablets will take the experience to a more compelling level.
    Even so, Canonical has proven that its work with Ubuntu Core and the “convergence” paradigm is impressive and promising.

    Boa tarde,

    Na minha sincera opinião estes tablets a correr Ubuntu (assim como os smartphones) são apenas para o show off. A Canonical não tem força para fazer isto vender. O software não tem muitos users (comparando com a concorrência) e não tem os conteúdos da concorrência. A Canonical para ser bem sucedida nisto tem de conquistar os vendedores de retalho, os clientes, os programadores, os fabricantes, etc. É uma batalha muito maior que simplesmente meter o sistema a correr nos dispositivos.

    Empresas como a Microsoft e a Amazon tem dificuldades em penetrar neste mercado, fará a Canonical. A Amazon até foi pela via desesperada de correr uma versão modificada do Android e nem assim. Para mim este show off da Canonical dura uns meses e depois nunca mais se ouve falar deles. Mas isto é o que eu prevejo. Veremos como o mercado reage.

    World’s First Ubuntu Linux Tablet, Aquaris M10, Available For Preorder From $290

    Have you ever wished that you could have the full Ubuntu Linux experience in a more portable, personal form-factor? No, we’re not talking about Ubuntu on a laptop, but on a tablet. If that’s been a dream of yours, you’ll soon be able to sample Ubuntu goodness in a 10.1-inch form-factor at the retail level. Canonical, the makers of Ubuntu, have teamed up with Spanish device maker BQ to bring us the Aquarius M10 Ubuntu Edition tablet, which runs Ubuntu OS version 15.04 (Vivid Velvet). What’s great about Vivid Velvet is that users are presented with a touch-centric interface when using the tablet by itself, and it converts to a desktop mode when you attach a mouse and keyboard (that sounds a bit to us like Continuum on Windows 10 devices).
    On the hardware front, don’t expect to find anything special here with the two tablet models that are currently available for preorder (HD and FHD). The HD tablet features a 1.2GHz quad-core MediaTek MT8163A processor and a 1280x800 resolution display. The FHD ups the ante with a 1920x1200 display and a slightly faster 1.5GHz version of the same MediaTek processor.

    Shared features among the tablets include 2GB of RAM, 16GB of internal storage (11.2GB of which is usable), a microSD slot (supports up to 200GB), Bluetooth 4.0, 802.11n Wi-Fi, GPS, 8MP rear camera, 5MP front-facing camera and a 7280 mAh battery.
    Both variants of the Aquarius M10 Ubuntu Edition tablet are now available for preorder, with the the HD model priced at €259 ($290), while the FHD model goes for €299 ($335). If you preorder now, your tablet will [hopefully] ship during the second week of April.
