I had a very similar experience. I stick to a 10 keyless keyboard (no numpad) but I gave up on the trackball. I use a wireless trackpad now because I ended up with pains in my thumb after a couple years of the trackball. I could probably have used a better quality trackball but the selection is/was limited. vim support in IntelliJ is pretty good these days so that's a huge help too. I had to abandon emacs and my claw movements early in life...
