Not me! My 64gb ATT has worked without flaw. Being a iPad1 owner, I wondered if I would really be that impressed the iP2! Let there be no doubt! The iP2 is more than a worthy upgrade. The one single items that I feel has seen the biggest performance gain was the Internet browser. All seems faster and smoother. No doubt that download speeds are faster, don't know why, but they are much faster. The graphics are much improved and as I use my iP2 the most for doing the Internet, I am not disappointed. Anyone on the fence that is wondering if the iP2 is an upgrade over the original needs to not wonder any more and just get it! I think apple did a great job and only disappointed that Apple is holding back and not allowing this device to be all it COULD be! Still too tied to iTunes and lack a proper file system that allows me to set up folders, etc.
