I've said this about thin clients in the past, they used to run Windows CE (that palmtop OS) and basically act as a minimal slave to a terminal server session.... and I'll say it again..
IF ANYONE PUTS THAT SHIT ON MY DESK I'LL PUNCH THEM.
I guess, what I am getting at, is, though cool minimal technology - would you prefer a shiny designed-for-gamer powerbox.. or an intel atom based device designed with cost and size in mind as paramount?
As much as I'm all for portability - speed comes first.
