If you love apple go for the mac if not HP.
As usual, MBP lacks in performance, but the design is flawless.
HP has extra 250gb space, but you can get 2+ TB external harddrive for $100 through Amazon.
You can later upgrade the MBP RAM to 8gb, but you will need to remove 2gb from the HP when you upgrade.
The graphic card would matter if you play games and other design work. Take Mac OSX Lion if you're a graphics guy.
I'm using a 2010 MBP i7 15inch 500gb SSD. I'd say its nice appearance wise. Haven't seen the HP.
