I think it's actually the opposite. My folks also have a couple of years old computer, which was on 800x600 default. Some time ago they complained that they couldn't see all sites properly on their computer, so I told them to change the resolution. "Change the WHAT?". So I did it for them next them I was there.
So I think it's the less tech savvy people that are still on 800x600 or only have a computer to email people and when the old lady has gone to bed - surf for porn. The people that have no clue what a TGP, link list or AVS is. When they type in "PORN" (the caps-lock was accidentally on when the computer was delivered, so they think all computers type like that) they always end up at a place that charges $29.95 - free PORN doesn't exist, so they think.
Ok, I went a little overboard at the end - but my basic idea was there
Cheapskates = more tech and Internet savvy, they know where the free porn is.
