There are quite a few threads where this, and similar, topics are under discussion. Obviously, with the nVidia issue, this is of particular interest. I'm a recent switcher, and the very pleased owner of a MBP. As yet, the nVidia problem has not emerged (which is not to say that it won't); however, I'm still well under warranty, and plan to augment that with Applecare. My experience with Apple in the customer care department has been excellent thus far - it is one of the main reasons I switched. Twice an iPod (within warranty) died, and it was twice replaced without any difficulty.
So, I'd say, the choice is yours. The MBP is a superb machine, beautifully designed, aesthetically attractive, high performance spec, powerful and has a superb screen. If you buy it, you're covered under warranty if something goes wrong. If that still sounds like too much hassle, then I suggest you try the MB; their owners swear by them and tend to be pretty happy also. Cheers and good luck.
