To my knowledge the only advantage of a 64bit OS as of right now is the ability to use 8 gigs of ram.
Only those who plan to install or utilize anything more than 3 gigs of ram in their system would generally use the 64bit OS. 64bit supports 4 gigs and up. I've seen systems running up to 16 gigs of ram in their system. For reason I dont know.

it supports LESS than 4G also
I disagree with your over all statement though. I have, more than once, dealt with embedded systems (at work) that are 64bit buses, with MUCH MUCH less than 4G of ram.
You say, well, that's at work. Same thing applies at home. I ran an apache web server from my house for along time. 2G of ram...but I choose to run the 64B version of linux to handle it
My mistake. Didn't clarify that. I guess I meant if you want to utilize more than 3gigs of ram then go with 64bit.
BTW, is OS X 64bit or 32bit?
