That's funny, I'm the opposite. I'm generally unlikely to sign up for any site or service that makes me create and record yet another username/password combo.
That's not the first page of the site, It's a link to a spec page comparing the different models available.
IMHO, it doesn't differ significantly from this page: http://www.apple.com/ipad/specs/
I hear ya. It might be true for some people that they don't need a GPS, but having an always in my pocket GPS whenever I'm in an unfamiliar neighborhood reduces my stress level a lot.
Isn't Raspberry Pi also pretty much a proprietary design? Certainly the Broadcom chipset they use isn't available to the general public, nor is information about the chipset available without an NDA.
The Broadcom chip documentation is not generally available. Beyond that, you probably can't even buy the Broadcom chip.
The GPU (the bulk of the chip's compute power) is a black box with a binary library that works with some versions of Linux for the time being but will eventually be abandoned by whoever is wrote it. That is just the current state of the world for embedded GPUs.
But looking outward…
The Raspberry Pi Foundation commits to documenting the exposed hardware of the SoC in their FAQ. (Think GPIOs, analogs, serials, etc).
I got the impression that the Raspberry Pi Foundation was thinking about how to license the design, perhaps a CC, but I don't see that they have made a decision. It is in many ways it is moot. They could give you the Gerber files, but you wouldn't be able to get a BCM2835.
I assume this installs itself as a replacement launcher. In which case it'd be the first thing that come up every time the phone boots. I'm pretty sure the "login" step they show is just on initial install.
Aside from the new logo, it looks pretty much identical to how the Android Market site has looked for well over a year.
It's also logical that it would resemble the Apple/iTunes store, since they both serve pretty much the same purpose but for different platforms. Barnesandnoble.com and Amazon.com both look substantially similar for example.
To be clear, the limit for the main application APK is still 50K. This change allows developers to also host on the Google Market servers up to 2 supplemental files that are up to 2Gigs in size.
Basically, this provides a better supported, more reliable, more standardized way to accommodate the already common idiom where many Android games will, immediately on first run, begin downloading the game assets (graphics, sounds, music, etc).
