Probably due to more support required.
Even linux in 2008 isn't as easy to use as windows. Someone who knows windows well and sees that option at Dell thinks "oh sweet, I'm gonna get linux and be a hacker! neeeaaaahhh" only to get it and not have a clue and bug Dell with every problem. It's just not as easy to use. I like to talk a lot of crap to a friend who loves linux, just to give him a hard time, and even he will admit something like "linux users spend way more time just getting things to work than windows users".
I'd like to think spyware/malware on the average users Vista pc is far less than XP do to updates that many don't bother with, good built-in protection, and most importantly no admin account as default.
