Shiny!
Just got myself a new computer, and is it ever pretty! There's cool LCD racing stripes down the front, a nifty window on the side, and the monitor is shiney silver. Oh yeah, and it has a fast new processor and more storage space, too.
It's taken me most of the day just to get the basic programs up and running. I'd have to say the strongest selling point of pre-assembled machines would be having all the drivers pre-installed. If it weren't for the integrated video cards, slow hard drives and other less-optimal parts, it might even be worthwhile. But then I wouldn't have my shiny souped-up case, so what'cha gonna do?
