Definitely interesting... I'm definitely not the market segment for something like this (I'm totally fine with my PC, thank you) but hopefully this can bring some of the console kiddies a decent, non-rapey gaming experience.
Looks pretty cool. Another feature I can see is more mobile applications - it's pretty hard to carry around a decent gaming rig (mine weighs 25-30 pounds) but this looks much more compact. Also, the prospects of a console that works like a fully-fledged PC are certainly interesting. Only time will tell though if it's actually worth it over, say, a decent laptop.
