I know for a fact that this track pad can support 4 fingers, so it's clearly a software issue.
It makes you wonder if this has more to do with Apple wanting more money more often than ensuring customer satisfaction. There is nothing wrong with that, as Apple is a company. I just thought things might have been a little different...
confirmed.. in linux using the new bcm driver I can track 4 fingers and have set up a pretty insane number of gesture commands for use in maya and houdini as well as generic 1 finger tap. 2 finger tap and 3 finger tap (with drag)... l palm detecting works (and is configurable)...
as a side note, is there a new boot camp update? because thats another long standing issue with the 4,1 mbp... the touchpad drivers apple provides are unusable...
it's sad I'm using linux as a primary OS based solely on the trackpad support... I have and use a wacom and a mouse, but sometimes I don't have access/room for them, and it's a sad sad fact but houdini and maya run like crap on OS X.. I wish apple would let us turn off the quartz stuff for the interface while leaving opengl on... it messes up so many apps.
cheers
