Hello! I am definitley set on buying a Macbook Air. I was currently going to wait for their next upgrade but I just can't resist these beauties any longer! I am currently using a Gateway notebook with a 2.0ghz AMD turion64 mobile processor. I have nothing bad to say about it but I am curious about the speed of the Air. Since it is duo core, is it 1.8x2? Or do both of the processors add up to 1.8? I played around with them at the stores and they seem much faster than my laptop which has a faster single processor. I am constantly checking this board and I've heard some mention how it seems faster than a MBP. Can someone clear this up for me? Thanks! ....Go Apple!
