Getting down to the wire for pulling the trigger. so far, it's 20" iMac with wireless kb&m. The burning question is do I go for the VRAM upgrade for $68? Don't do too much gaming at all. Mostly this will be for home use...mail, surfing, photos, some home movie archiving, video conversion for the new iPod maybe. I don't really know what the VRAM is good for, so maybe if I don't know then I don't need. Does the VRAM make a big difference on resale value? I'm just concerned that since this will be my first non upgradeable computer, then I should go all out (as much as possible) on the front end.
