It's funny you should post this thread, as I was just thinking about this. Before being a regular reader of MacRumors forums, I would have NEVER thought to put something like Wrapsol or the Moshi Palm Guard on my computer (and in fact, just used a sleeve for my BlackBook). Now I'm starting to wonder if I should buy something for my new Air... I can't decide whether it's overkill. Anyone regretted NOT using a skin?
