In my previous mini review, I spoke about a problem I had with my original MBA. It appeared to overheat and have kernel problems all the time. Apple swapped it, and my new one appeared to be fine. It worked great until I reinstalled Parallels. My new book started to show the same behavior.

It turns out that you must use a special build of Parallels with the MBA. Once I upgraded to that, my problem went away.

So sorry Apple! It turns out the my first MBA was just fine.
