I'm experiencing the problems described here, basically the trackpad has spurts of spurious input, but the problems are fairly intermittent. I've kept the system usable by deactivating many non-critical gestures, like zooming, three finger drag, etc.
Are there any visualization or tuning tools for the Mac Book Air's trackpad? It'd be useful to simply get a graphical record of the trackpad's input over a period when it was miss-behaving.
Are there any such tools under Linux if not under Mac OS X?
