I must be the only person on earth who has good encounters with Geek Squad. I mean, I know my computer stuff, generally tell them what's wrong, and my agent quickly confirms my suspicion and tells me what needs to be done. I've never had an issue with it. Obviously you don't want to have to deal with them because that means something is wrong, but they've always taken good care of me.
Me, too. No troubles at all.
I'm posting this from a Dell desktop, and I love this machine to death. It's been great for me.
After posting, I found out that revkah has already posted most of what follows. Oops.
So far, in our family, we've had good experiences with three different brands of desktops/laptops. It's really going to be about finding something that you're comfortable with. You'll get a good deal, especially right now, in the post-holiday shopping period.
Just don't get the dude that pretended to help us with our microwave shopping. He claimed to know one model, which wasn't where our questions were, and he tried to fake the rest. Get a salesman like that, and just head out the door.
