i use my Macbook (C2D 2ghz, 2gig ram) for college. i goto vega and it is all i need to get through the multimedia leg of my 3 year course basically using it for Adobe illustrator, dreamweaver, indesign, photoshop, and flash. also use aperture
i use my mac for everything else to (music, movies, internet). i have a fairly mean PC that has been sitting around for 4 months since i got my Mac.... poor thing
Internet - web publishing - Limewire - iTunes - movies - bubbles - basically everything I do on the PC ... and its in the lounge next to the aircon set on 28 degrees where the PC is in the back room at around -10 degrees.. so yea. Still like the PC as it has 3 LCD monitors and that is great for mucking around especially for web publishing..

other chat clients.
