I have an HP laptop that I'm happy with but it's probably best to read different reviews and then go with the one you like. You could always stick with Dell if you wanted (they make laptops, right ?).
As for women screaming, I find tv shows "appreciate" the screamers. Ellen had two women competing for a prize this week who were a pair of screamers and she said she liked their energy. I've read before that the contestants on Antm have to re-film if they don't greet Tyra enthusiastically enough. Me, I would feel like an idiot, and I think those screaming look like idiots.
