Depends on your time table. If you are several months out, I would totally wait until Leopard comes out and buy a MacBook Pro. Rumors have it (note I said RUMORS, people) that February could see BluRay drives in Apple machines. Not sure if that means Mac Pro only or if they could find their way into the MBP, if it even happens. If it's just a matter of having the latest and greatest thing, give up. Something will always come out just after you bought your machine. :D I would simply wait until the next MBP update that happens after Leopard is released if you aren't in any big hurry.

If your timetable is gotta-have-it-right-now soon, I would strongly suggest that you at least wait until MWSF (first week of January) because that's when they announce a lot of good stuff.

I am not big on the MacBooks because they have integrated graphics rather than dedicated vRAM. That being said, a friend of mine just got one and she loves it. She doesn't do any heavy lifting with hers though, so TIWAGOS.
