I tried searching the forum posts but did not find this one. I'm looking at buying the 21" iMac and trying to decide between the 2 models. The cheaper model has the smaller hard drive, but 500 gigs is plenty for me. My only concern is the nvidia 9400 graphics. I don't play games on my mac. I mainly use it for the usual - internet, email, iWork, MS Office and iLife. Probably the most graphics intensive thing I do is iMovie. will the cheaper iMac do me? Thanks.
