I paid a lot of money for this samsung, now I can't tell if its not responding to my commands because the system is unresponsive (half the time i think this is the reason) or because the touch sensors are not sensitive enough to recognize my command! further, half the time i try to switch tabs in a browser it closes the (system says i hit the x button on the tab). Poor touch accuracy! Beyond annoying...WTF gives..? I've got $700 into device and case!!!!
