I'm starting to think about replacing my laptop soon. It's old and starting to lose some functionality. I've been using Macs at work frequently and really like the design of the MacBook Pros. Now that the new Airs have been around for a few weeks, has anyone encountered any problems or have complaints about them? I know the previous Airs had problems with heating and hinges(?). I have heard that the heat will only get "warm" but that was from only one review. So, what are the new Airs owners compaints or concerns. If I do decide to get the Air over the MBP, it will be the 13 inch one. Most of its use will be note taking in class and some light programming. It will be used as a second computer.
