Here's a little bit of advice if you buy a Dell laptop.
While you're logging on, buying all the accoutrements and gushing about how wonderful they are...make sure that you buy six or seven battery chargers for said laptop...because that is the greatest scam that I've ever seen. I'm on my THIRD charger now and I've had my Dell laptop for about three years.
So...yeah. I'm buying a Mac. Dell can go fuck itself.
