Okay I know this makes no sense! I am playing with a MBP - lovely keyboard, nice screen, not massively heavy and fast. A MB is sufficient for my needs but I don't want plastic as it looks so unprofessional. The MBA seems ideal as it has a similar form factor but is more compact. So I am not sure! MBA - lovely, cheaper (just),light MBP - lovely, more expensive large. A 13" mbp would be perfect but that is unlikely to happen. BTW I found the smaller button on the MBA annoying - kept missing it - how have other people found it?
