I bought the 8GB A500 from bestbuy on cyber monday. I like the tablet but found one dead pixel on top right corner when the tablet is held horizontally. I've been calling best buy a few times over the past few weeks to see if they have one in stock so I can exchange it. But since the cyber monday, they no longer carry the 8gb one. I have until 1/24/2012 to return but I just want to exchange it.....Any suggestions? Thanks.
