I have owned both a macbook pro and currently have a macbook
Pro = 1.83ghz CoreDuo 15.4'
Ups - I do VJ work and needed the grfx card.. the screen size was of obvious benefit but i always use a secondary monitor anway for production work.
Macbook = 2ghz Core2Duo 13.3inch screen
Ups.. lighter than the MBP
Downs - screen size
performance blisters on both of them, but the current MB i have is WAY WAY faster than the MBP i had mainly due to the 64 bit chip.
if you want it for DJing etc then the MB is the way to go, DONT spend money on getting the super drive.. esp when external DVD burners are so cheap..
DO spend the money on extra ram it makes a LOT of difference in a MAC
if you're gonna get one then you can either wait for Leopard to arrive or get a 'demo' version later.
I was thinking about quad core lappys but this link set my mind at rest

an external HD will be worth your while, dont get a USB one though. firewire all the way.
iWORK 08 is now bundled with the MB and is an absolutely brilliant set of apps for media creation.
Now, as techmouse will tell you im a bit of a fanboy. my reasons are:
reliability - NEVER EVER EVER had a problem with any of my macs
speaking of which
DONT bother with the APPLECARE until the end of the first year as your machine is under warranty, its a bit of a trick by apple to get people to pay for it at the beginning, they get 3 years... or rather actualy only 2 years past the end of the standard warranty NOT 3 years i.e 4 in total.
PLUS
bootcamp means you can have windows on the MB as well, and it ISNT an emulation... my copy of XP is blazingly fast on my MAC and ultra reliable.
try getting second hand as well. substantial savings and hard to beat.
IMO of course.
