According to Wikipedia the Raspberry Pi uses the ARM1176JZF-S core which is an ARMv6Z architecture. It should be similar to the ARMv6K as it most notably lacks multi-core support. It's still an old architecture, of course, and I agree that the Cortex A-series is a much better choice as a development platform, whether it's the currently popular A8/A9 or the upcoming A15.

It's a generation-lagging ARM11 -- Windows and iOS don't support these kind of chips anymore (called ARMv6) because of major lacking functionality. The ARMv6K (which I'm not sure the Pi uses) is probably the minimum you'd want to use, and I know the ROS ARM port was retargeted to ARMv7 which has been out for almost 3-4 years now.

The PandaBoard, which is 179$, so definitely more expensive, is a much better platform for such a port -- it's an A9/v7 (successor to A8/v7, successor to ARMv6K, successor to ARM6...) and has dual-core, 1GB of RAM, a GPU, a DSP, and more... still a bargain for 179$ if you ask me though.

It looks like the model B boards are now in manufacture. http://www.raspberrypi.org/archives/509

There are only 10k being made being made in this batch and demand is really high, so I doubt they’ll last longer than a few minutes.

With only 256MB RAM available, I doubt Windows 8 will ever run on it although Windows Embedded Compact 7 might.

I know the reactos arm port is still a way off, but this could be a golden opportunity for reactos.

At $25 per computer, they’re gonna sell hundreds of thousands of these things and most buyers will be enthusiasts/developers.
