If I could put OS X on any new computer system I purchased:
1) I would buy a MacBook if I was in the market for one. They're nice laptops and the price is pretty good, as is the overall quality
2) I would look at the MBP and also shop around and look at other brands.
It's slightly more expensive than it should be, although to tell you the truth, people who say that the MBP is a ripoff compared to what they get from other companies is exaggerating a bit. People complain about the graphics card in the MBP, but there aren't many laptop graphics cards better than the one in the MBP. The entire market is moving very slow right now, so the mobile graphics card that was high-end 1 year ago hasn't fallen too far behind.
