Other companies have tried and mostly failed with laptop/tablet hybrids. But maybe Apple found out how to pull it off properly. If you look at where we are performance wise, the time is right!
didn't Tim Cook say the hybrids are like toasters/refrigerators and made it seem like they would not move into that direction
personally, I hope the Air doesn't go Retina mainly because 97% of web content is not retina optimised and a lot of things look blurry/distorted...the text is already sharp enough on current air
Heres hoping the Air stays the same just gets lighter/sleeker
I just can't see Apple changing Air too much considering how many people use the machine and have come to depend on it and so use to it.
