Excluding a purpose-driven reason like CPA or photog, why do you have a desktop computer today instead of a laptop? I find it much more pleasant to sit on the couch with a laptop unless I'm doing serious work, at which time the laptop goes on the desk. We have 5 computers in our house and not one desktop. I can't think of a reason why I'd want to sit at a desk to use a computer "casually". What about you?
