Now that the MBA has been out in the wild for just over a month, I am wondering what peoples' impressions are. I find it very useful, perfect for my needs, and just what I expected. I know that others have suffered through some Rev A teething (cores shutting down, loud fans, etc.). Let's hear from the owners out there. Those who hate the MBA and would never buy one need not respond please. This is a thread to inform those for whom the MBA might be appropriate.
