I need some advice here... I am running on a 4 year old iBook G4 which has had tons of logic board issues in the past. I had a 4th logic board replacement a week before applecare ran out 11 months ago and since then it has been working fine. I figure that soon it will happen again since this occurred so much. So I was planning on waiting for Rev B of the new macbook so all kinks could be worked out (I havn't heard of any though). But now I am seeing these Live.com rebates and I am thinking of just doing it now. I would save about $300 when you combine the cashback + no tax. On the other hand if my computer can make it till the summer then I would most likely have revision B and a new iPod (the savings would add up to about equal I think) Is it worth just doing it now or should I hold off till this computer crashes and hope Rev B is out by then? How long do you think this Live.com offer will last?
