Well, I am sure price will be pretty crazy, but it has the potential to be fairly powerful. It has a Yohan CPU which performs about on par with an X23800 (the 2Ghz version anyways) and the nVidia 'Go" cards are pretty freaking impressive for mobile GPU's so....
I don't see myself in the market for one, but for someone who wants something kind of in between a laptop and a desktop, it would be pretty cool, and it isn't something you could recreate building.
Saw it last week.. It's old, move on.
A whole week ago! For reals!
