I also have a 15" MacBook Pro, and I love it! Mine is a little more than 2 years old, so the new ones are much better - faster, more hard drive space, etc. I'm coveting one of the new ones for sure! I sometimes think I would love a 17", but I agree with Lynnette that it would probably be a lot to lug around. The 15" is a good size. The next one I buy, I hope to get the fastest processor they offer, and the biggest hard drive they offer. All this scrappy stuff can be stressful for a poor little computer!
