My touchpad works okay but I prefer to plug in a usb mouse (cost a few dollars at a pawnshop).
I find a trackpad makes it too easy for me to do actions accidentally:
* Press a little too hard
* or press too suddenly
* or move my finger a tiny bit just before I press...
Thus causing me to click where I did not intend. I move a file, or open a program, or navigate to an advertisement. Then I have to undo it.
Moreover the pointer tends to disappear after a few seconds idle. Then I have to search all over the screen for it while moving my finger around the trackpad.
With a mouse the pointer behaves as I want it to. I believe you're better off if you forget the trackpad.
