Yesterday, my PB developed a nasty habit. The trackpad flakey-unresponsive. It has gotten worse and worse to the point that in the last five minutes, it has become wholly unresponsive. This goes for the trackpad button as well. I've tried the Apple Trackpad Reset Method of putting my palm on it for five seconds and then lifting in one smooth motion. I've also tried rebooting, sleep/waking, setting to Better Performance. Any thoughts? Applecare expired over six months ago, so I don't have that route anymore. I'll take it in to the Geniuses tomorrow or Wednesday, but I don't know what kind of luck I'll have with them.
