I'll be getting two or three of these for screen scraping prices from various travel supplier's sites. This is something we use multiple processes on a vastly overpowered 500W PC to do nightly at the moment. It seems like the perfect solution for screen scraping, which is network heavy and CPU light. Doing all this for <3W with little heat and no noise would be fantastic.
Hopefully Mono will be ported to compatible linux distros so I can port my existing C# code over.
For a personal project I'd like to figure out an Android phone controllable music server. A 60gb SSD hooked up to one of these as a music server, then others hooked up to various speakers around the house as clients, with the phone acting as the controller.
Then there's the idea of an 'info display' which would be a cheap HDMI display set in 10" photo frame with a R-PI on the back. This could show yesterdays website visits, current site visitors, twitter mentions, facebook likes, competitor actions, news, unread emails etc. Lots of possibilities with some scripting.
I can see a whole ebay sub-industry of cases to house projects that include these things springing up.
I think this is such a great project. Hardware has largely become a 'hands off' thing now, and this brings it back to the days of the BBC Micro, but with current specs. I can't wait order a few of them and tinker without caring if I write a few off.
