No, no, yes and no.
I love my MacBook. I've been very, very happy with it from day 1. I wouldn't say no to a MBP but I certainly don't regret not splashing the extra cash. This suits my needs, I surf for hours a day, play a lot of The Sims 2, bit of Photoshop, MSN, Yahoo, Skype, and a touch of web design.
