I have a macbook pro C2D 15" laptop, and all i can tell you is that it is the best laptop I have ever owned. It is fast, reliable, 1" thick, light weight, great battery life, built in blue tooth and a/b/g wifi, 120gig HD standard, 1gig of ram standard, and I run OS X, Windows, and Linux on it flawlessly.
Oh yeah, the back lit keyboard is pretty pimp as well, and the ambiet light sensor will kick it on if it senses there is not enough light to see the keyboard. It is very nice.
I run windows natively and via parallels desktop. I am getting ready to makea virtual OS of Unbutu here in a sec.
I disagree about the sonys, I don't think sony makes a good product anymore and I do not recomend buying one.
And yes, it will be able to run vista in future releases of boot camp, etc. However, vista sucks big time and I would recomend just staying with windows xp for now.
