Home automation? Use it to control the lights? Hook it to a small screen in the kitchen and use it to look up recipes? If you spill grease on it it's not like you're out the biggest investment in the world. A display ticker for your help desk tickets?
The best robot I ever put together was when I got two broken Roomba's off ebay and combined the parts to make one working one, lol. I love the idea of these boards though, am just sad that if I got one it'd probably sit on my shelf for years, in between other projects, while I cry over not having enough time for it.
