Well good for you! In my case Dell has a horrendous customer service with the school district I work for (and I live in Austin so you would think Dell would do well at home right??). We just replaced about 150 computers since september and a good 20 of those already have hard drive problems. The issue? it took Dell 2 months to come and service them!! (I supposedly can't touch them if they're under warranty).
Anyway in my opinion, as well as their machines might be built their customer service is getting worse everyday.
