I too had bad problems with disk lag on my iMac rev. A. The two things I did to increase the speed of drive I/O to the very acceptable latency was; 1: 7200rpm drive (this helped the most) and 2: More ram as others have mentioned, this does work (320mb instead of 192mb).
A couple of my friends have also done dedicated swap partitions and gotten even more responciveness. Other's here have also suggested this.
I don't mean to be down, but the track pad on most modern apple (and even wintel)portables are far superior to any of the trackballs I have ever used. I've been playing around with a PB 150 (possibly one of the worst mac computers), which has a trackball. The computer is almost not usable because of it.
Also, a track ball in a laptop is a very bulky, space consuming item. If they make it too small, you have pathetic control, if they make it nice and big, the laptop has to be huge (certainly not the trend currently).
