Snap ;) Oh, and a pocket voip p2p wifi mesh phone would be nice. Though the latency might be crap over too many hops and I am not entirely sure how well it would fare in really huge city-wide networks of the things. :)

Hope you're thinking of a self-contained LCD/touchscreen off the shelf. I've been trying to ascertain how to hook up a small LCD and capacitive controller over the LVDS/DSI port and I'm not getting a lot of information. Asking on the forum isn't getting much data. Is there SPI or I2C on the flex connector? Nobody knows. How about power for the LCD backlight? Oh, the 5V rail is limited to 1 amp. How about the DSI driver? Broadcom won't talk. You start pressing for details about this and then the stance swivels to "Hey! This is an educational computer! You shouldn't be working on wacky applications like this!" I don't see a lot of people proposing educational applications for the Rpi so far. Just people that want a cheaper Pandaboard.

  From what I understand, the idea is that the first few batches will go to hackers so they (we) can get to work stress-testing and creating with these. After we're done, they'll sell the next batch to the education market hopefully with the new tools/accessories that the hacker community had come up with.

    Can't create much when we can't see schematics and ascertain if the I/O ports carry what we need. And if there was a deficiency, they've publicly said they won't respin boards. Not a very encouraging situation.

      They do plan (and will have) IO extensions ala Arduino. I can't remember what they call the daughterboard they're releasing. Mainly what they want is software and cases. It's meant to teach kids computer programming and software basics outside of the Windows and OSX "don't worry about it" mindset they're currently growing up in. Robotics and extraneous hardware design is outside of their current scope.

        If you're thinking of the "gertboard" that was announced, that's a breakout board that is connected to the Rpi over a SPI line. So it's not turning GPIO lines off the processor into usable connections, it's just an I/O extender. You could be using that exact same board with an Arduino today and bit-bang your SPI commands.
