I am wondering whether to buy a new Macbook Air or wait for the new Macbook Pro. The issue I have identified is that I have an old 27" Apple Cinema Display that I want to continue to use. I believe this will plug into the Thunderbolt port in the MBA. And there is only one such port. The question is, does that matter (at the moment I have no Thunderbolt peripheries)? In other respects, I think either would be fine (I don't travel that much, but I also don't need much computer power since I largely use my computer for email, text processing and web browsing).
