After more than a year, I'm totally fed up with the numerous limitations of my iPad and wonder if an Air would be a better bet than my current set-up of a MacBook Pro and an iPad. But looking at the specs (Core 2 Duo, 1066mhz frontside bus, 2GB RAM etc.) is like looking at the specs of an old MacBook. So, thickness and weight aside, how old is the technology in the Air? Will it be like going back to my old PowerBook?
