Picked my wife up an HP at a black friday sale last year. Still going strong but worst trackpad/soft buttons I've ever seen. Sounds cliche but I absolutely love my mbp's. Been using them in place of a desktop for years and have barely noticed. The way I looked at it, I was getting two machines for the price of one since I can dual boot in to windows or osx.
Of course I just ordered a new mac tower since I'm barely mobile.
