A year ago I went down the rabbit hole of looking into custom trackball-keyboard integrations. Ploopy, Charybdis, Dactyl, CCK-ball, etc. My final boring conclusion is that what I had already been doing for the past 20 years is much cheaper and gets me 99.99% of the way:
All you need is a regular ~$50 trackball and a regular ~$100 keyboard without a numpad. (You can have an overlay for that, if you need it.)
As someone else pointed out, this new trackball will make you move your fingers (and wrists) significantly off home row. If you do that in one direction or the other doesn't really matter.
If this works better for you than a Logitech or Kensington trackball, sweet, use it. But so far all the reviews are like "I've never used a trackball, but this looks cool". We've had this technology since the literal 1990s guys.
