I'm definitely not getting a Macbook with the battery life it has now... maybe after Penryn. So right now I'm looking at these three iMac configurations: 1. 17" iMac refurb @ 1049 2. 17" iMac w/edu discount + 2.16Ghz C2D + 250 HDD @ 1257 3. 20" iMac refurb @ 1299 As you can see, choice one is a good deal 'cause then I could get a decent display with the $250 saved, and still have mulah left over. 2 and 3 are the same, except for the difference in display size. I'm leaning towards the 20", because I don't want to have to buy a second display to get the same screen size as the 20 (what I want). 1299 is a little much for me, so is the screen size worth it?
