So I've had a PS3 for a little over a month now, and I've had problems where my controller stops responding for ~3-5 seconds. I thought it was just because I bought it used, and maybe the previous owner had abused his controllers. But then I read online that a number of people had the problem. Some chalk it up to faulty hardware, some say it's interference from other wireless devices. I figure my Wiimote (also Bluetooth) and 360 controller (same frequency band, though not Bluetooth) never have any glitches, so it's a shoddy excuse either way. Is this a bigger problem that people aren't talking about?
