Well im considering buying a refurbished macbook off of the apple store site sometime this month hopefully..I have been reading all the other topics about others buying refurbs and other various issues people have with their macbooks...anway my real question here is it worth it just get the 2.0ghz model over the 1.8 model? i mean they are only $50 apart in price....how much of a speed difference between the 2 are there...would the 2.0ghz be more realiable. just looking for feedback from other buyers and current mac books owners....
