Maybe he doesn't have cable or DSL in his area or he feels it's to exspensive for the amount he'll use it.
Where I live, I've got cable (Beep! Beep!) and there is DSL but only from a small local telco in their own small area. So, DSL is not a real option here. Also, I can get dialup for between $5-$10 a month compared to $50 for Cable.
IE, there's lots of reasons.
