Well, I only bought my 13" MBP yesterday, but my reasons for purchase were:
- Performance
- Portability
- Battery life
- Minimalistic looks
- Build material and build quality
- Runs both OS X and 64-bit Windows 7
Negatives:
- This is my first Apple laptop with a Magsafe power connector, and frankly I can't see how it would come out if the power cable were tripped over (because the magnetic connection is so strong). It's going to take the whole laptop to the floor, just like the old connectors did.
- Glossy screen - but a matte screen cover can be purchased for US$35.

Reviews that I'd read stated that the MBPs get hot. Yes it gets warm, but not as hot as my G4 iBook does. Although maybe I haven't thrashed it enough yet to be able to make that statement.
So far the laptop has been excellent. Leopard and Windows 7 run well on it, as do some older games. My display has one dead pixel on it, but it's not too noticeable.
Yes, there are lighter, cheaper, faster, higher capacity notebooks out there - but in my opinion (and I'm no Apple fanboy - my main computer is a desktop PC), the MBP is the best balance of all of these things of any notebook on the market.
