Today I was finally able to spend some time with Motorola’s Atrix 4G and its webtop dock. For those of you who don’t know, earlier in the week Motorola announced its first Tegra 2 based smartphone: the Atrix 4G. Motorola later announced another Tegra 2 based smartphone, the Droid Bionic, however the Atrix 4G is its flagship smart/superphone.

Equipped with a full GB of memory and 16GB of NAND, the Tegra 2 based Atrix 4G has one very unique feature: it can be docked into a custom ultra thin notebook chassis and used to drive the notebook. Motorola calls this its webtop dock:

The webtop dock looks like an oddly shaped, ultra thin notebook. The Atrix 4G’s dock remains hidden until you flip it up. Slide the Atrix 4G into place and within several seconds you’ll automatically be dropped into the webdock app:

The webdock app is a unique environment. You get a scaled down version of your smartphone desktop on the left side of the display, while on the right side you get a full fledged Firefox browser compiled for ARM.

Browsing performance isn’t great, but it’s not unusable. The large trackpad supports scrolling with two fingers, or you can tap space to jump down a full page just like you can on a desktop/notebook.

There’s an OS X-like dock along the bottom of the screen that lets you fire up other apps (e.g. file system browser) or switch between open applications. You can also alt+tab between applications. Doing so will bring up an OS X Exposé like screen and not-so-smoothly animate tabbing through windows. It’s not a full blown PC experience, but it is honestly workable.

If there are apps within your phone that you want access to you can simply take the phone window full screen. You can even rotate it without moving the webtop:

Of course in this mode you are simply upscaling the phone’s 960 x 540 resolution to the webtop’s panel resolution (which I believe is either 1280 x 800 or 1366 x 768).

When you’re done with webtop mode, simply close the lid and your phone returns to normal. Motorola saves the state of your webtop so when you dock your phone again you get the exact same windows open as you had previously. Motorola insists that your webtop state is saved regardless of what you do to the phone as long as you don’t remove the battery - implying the webtop state is saved to NAND.

The Atrix 4G will ship with an entertainment center app that can be used in webtop mode. It’ll give you access to all media content on the phone and let you play it back on the webtop (or when used in the media dock and connected to an HDTV). NVIDIA’s Tegra 2 can decode high bitrate 1080p, however I don’t believe it supports decoding high profile H.264 1080p - only main and base profile content. We’re almost at the point where you can play anything on your smartphone, but I suspect it’ll take another two years or so before we are completely there on the high end phones.

Motorola ran through a quick demo of a Citrix app running on the docked Atrix 4G, giving us remote access to a Windows 7 PC on the smartphone powered webtop. The entire solution is clearly very functional, the question is whether or not it’s going to tempt users away from a netbook or other PC solution.


Windows 7 piped over the internet, display and interaction powered by Motorla's Atrix 4G - yep, a smartphone giving you access to a Windows PC

There’s clearly a lot of potential with these ARM based devices and over the next three years we’re going to see them get even more powerful. NVIDIA’s vision is a future where mainstream PCs are smartphones docked (perhaps wirelessly) to larger displays and input devices. Motorola took a major step in that direction at this year’s CES.

Within 24 months we will have quad-core out-of-order ARM based microprocessors in our high end smartphones. If paired with an elegant dock solution that’s affordable, will that be enough to go head to head with a netbook?


It works! But a Chrome OS Notebook feels quicker, which will win?

Personally I can see it going either way. While the docked smartphone is definitely compelling, one of the major reasons to want to dock a single device and use it in multiple locations is if the content on that device is 1) large, 2) plentiful and 3) difficult to move around otherwise. I’m not sure smartphones today have enough content on them for this to inherently make sense. Now when smartphones ship with 100GB of storage in a few years...

The biggest question in all of this is what happens to Intel and AMD as ARM tries to move up the chain. One thing is for sure, Intel’s Atom strategy, at least today, isn’t aggressive enough. For a company less than a year away from transitioning to 22nm, there’s no excuse for Intel to continue to ship Atom at 45nm.

    I get a taste of some pessimism in this article compared to the first where you seemed more enthusiastic and wrote "You’re looking at the smartphone’s first steps into the realm of the PC".

    You say that the browsing performance isn't that great and that the tabbing animation isn't that smooth. I watched Engadgets hands-on video http://www.engadget.com/2011/01/06/motorola-atrix-... and felt everything was buttery smooth. Could there have been some process in the background messing it up for you? Any comment on that?

    Maybe when hackers figure a way to replace Firefox with Chrome (which scales to all available cores, unlike Firefox), the browsing experience will be a whole lot better. Reply

    The difference compared to the N8 is that the N8 just runs the phone window (640x360) full screen and that doesn't look very good at all. Just look at the photo above with the Atrix doing the same at 960x540, still not good.

    So to be able to dock you really need something like Webtop or Honeycomb.

    The phone should insert into the chassis, not just hanging there like something begging to be broken off. Reply

    Or it could act as a high-end, glass, 4" big trackpad... Reply

    Good point. Whatever can happen, will happen. Reply

    I thought the same thing initially (in fact I assumed before seeing the pictures that the phone would be used as the track-pad on the Webtop accessory). But I suspect they abandoned that concept for 2 major reasons:
    1) Thickness. you'll note the entire Webtop is only slightly thicker than the phone and about 1/3rd of that thickness is display, so providing a port for the entire phone in the bottom portion of the Webtop would have increased it's thickness considerably.
    2) Flexibility. You'll note that the phone connector looks really design-agnostic (aside from a fixed distance between the micro HDMI & USB ports). I suspect this is because Motorola plans on a whole ecosystem of future phones & accessories that will be cross-compatible. Allowing several different phones to connect to the same Webtop is crucial for convincing consumers to buy what will likely one of the more expensive phone accessories out there.

    Just my guess.

    Good points. Also, the fact having the screen's touch detection of the Atrix constantly on when docked would probably get in the way of it recharging -unless it's a SAMOLED phone and they can have a few white arrows displayed on a black background. Reply

    I think its possible to run the digitizer w/o running the screen, so not much battery drain. But as previously said, the thickness of the keyboard would be a whole lot more if the phone should be used as a track pad.

    My alternative would be to slide the phone vertically, down into a pocket on the back of the screen. That way you would also be able to use the phones camera plus you could have the USB and HDMI in the bottom of the phone.

    I like that idea! (using the phone as a webcam)...still, that would probably break point #2 (cross compatibility with other phones). Reply
