So, the little sticker on the side of the A500 started to get on my nerves. A corner was coming up and I found that, like a tongue to a loose tooth, my finger was compelled to play with it so I went ahead and ripped it off. It came off very cleanly which was nice. I had never looked at it closely before but it does actually contain some useful information, namely the unit's power requirements, so I saved it. I like the feel of the unit without it!
