That Gateway thing is god awful, but the Blackbird looks mighty impressive.
Not everyone is going to like the Gateway all-in-one setup, either for the ugly looking power-brick or the radical design that makes it a little more difficult to work on for 'home techies' who like to tinker with their own machines. I guess it's like anything else that's radically changed, it takes some getting used to before one becomes entirely comfortable.
As for the power brick, I have places in my setup where I could easily hide it, but I guess many wouldn't and it would be a turn-off.
I do agree, however, on the Blackbird being an impressive unit...wouldn't mind one myself but future plans have already spoken for the cash, and then the case swap for my current rig will do me for a while...it more than adequately runs Vista and anything I've cared to load on it.
