Since getting my tablet, I've been babying the heck out of it... but today when doing the morning polishing of the screen with an eyeglass cleaning cloth, I'vd found what appears to be a tiny scratch. I'm baffled as nothing that could scratch it has come in contact with the screen. I haven't used a screen protector simply because I didn't have any on hand that big and hadn't gotten around to getting one. How durable is the Tablet screen supposed to be? I'm a little concerned that I got a scratch from sources unknown when I've been so actively trying to keep it pristine. It almost looks like a speck of something stuck on the screen, but it won't come off even with alcohol. I'm assuming it's a scratch that's filled in with something.
