well put it this way, I have a 5GB 2.4GHz MBP and I can usually keep about 10-15 browser tabs, itunes, ical, iphoto, photoshop cs4, a powerpoint, a couple word docs, and a mail client going at the same time and never notice a hint of slowdown. processor's at like 85% idle right now, and I'm using 3.33GB of RAM. (photoshop's not open right now).

VMs add significant RAM demand, but from the sounds of things you won't be doing much VM work.

Cool, thanks. I'll probably be doing a lot of heavy browsing with iTunes and multi pages documents open at the same time. And if your 5GB can handle what your doing, I'm sure my 4GB can handle what I'm doing.

By the way the reason I asked is because up until now I've been on a 2007 iMac that struggled sometimes to handle what I was doing. Which is why I got my MacBook Pro:D
 
A lot really. I can run a Windows 7 VM comfortably while running Photoshop CS4 in OS X. Keep in mind also that 4gb=3.75gb due to the 9400m stealing 256mb for VRAM.
