No big deal, I'll send it in for replacement.
But wait, there's more....
Apparently, if the sticker with the s/n number has peeled off, your warrantee is void. The sticker, on the back of the tablet, in the exact position as your hand would likely be while holding the tablet in portrait. Now I can understand this on a computer component, it sits in your tower and doesn't regularly get handled. My sticker peeled off less then a month after having the tablet, and I had no idea that it had until I tried to rma the tab. You can use the s/n sticker off the box if you tape it to the tab with clear tape, thankfully, but if you don't have your box or the sticker, even though you can view the s/n from the settings, it will be immediately rejected and sent back to you.
So just an fyi, keep your box with the s/n number safe, because that little sticker is eventually going to come off.
