I can live with all of the half-baked features of the latest MBPs (I have one for work, my home one is much older) but the false recognition of the overly large touchpad drives me crazy.
It's bad enough that I have to disable tap-to-click (which I greatly preferred - much more elegant) and it still mis-clicks if I rest my hands on it.
I used to think the MBP trackpads were a cut above everything else - now they're too big and the palm rejection is not good enough.
