What's the best thing to do with the MBA out of the box? Should I use it and drain the battery to zero or not even turn it on and just charge it? I want to treat it nicely from day one ... Also, on the same topic of treating it nicely, do you recommend a screen or keyboard protector? I had a keyboard protector on my PowerBook G4 (iskin). While it kept the keyboard nice and clean, I suppose it didn't give me the best experience I could have had with the keyboard itself. I now realize that I can't really read the keys because the protector is so dirty.
