You seem to be all over this forum. So, tell me. And I've posted this question already...but with money being a big concern, do you think I'll be happy with the refurb 12" 867 over the 1Ghz? $400 is a lot of money, and my main concern with the Rev. A is the heat. I work all day long at a PC desktop (ugh) so I use my laptop for watching DVDs, surfing the net, Email, photo storage. No gaming. So tell me, with the rumored much cooler Rev. Bs, will I regreat the $400 money saving?
