I was bored tonight, so I was browsing through the apple online store (looking to take the plunge for a Mac but likely going to wait until Santa Rosa at least). For the first time tonight, I noticed that the MB Pros have the option of upgrading to 3 gigs of memory (1 2 gig stick and 1 1 gig stick) Is this new? I don't remember seeing this before in my window shopping before. I'm wondering if this is a worthwhile purchase. The price jump is ridiculous ($750 if upgrading from 1 gig), so I'd probably hold off for now, although it is promising for future upgrades. Thoughts?
