To those who use it naked...

And I mean the iPad, not the nudity thing... although no judgement here...

So I've been using my iPad naked for the past few weeks, and I love how much better it feels without a case on it. But I only got mine a month ago, and I'm wondering how the wear-and-tear of everyday use is handled by the back of the device? I know aluminum is a metal, and it's mostly sitting on a wood desk or table, but I just wonder how the "pick it up, put it down," or spin it while on the table, effects the case?

I still love the feel of the aluminum on my hand when holding it. I have a best skins ever, but am hesitant to put it on. I had a bad experience with the feeling of those skins on my iPhone 4, and don't want to deal with that feeling again, plus it felt weird. I also tried a power support crystal, which i used for my iPhone before i got sick of the protector and went back to original glass, and found that while it works fine for the non-retina display, it made using a stylus much more difficult.

I've been putting it in an incase sleeve when i bring it into school (so every day). Does anyone suggest something thinner/lighter that they've seen or used? Doesn't need a zipper, or strap. Just something to put it in so other books/pens won't scratch the screen?
