How can that trackball (on the linked-to page) be ergonomic? It seems to require a sharp upward bend in your wrist, same as most other trackballs. I'd like to try one even so, as every single one of the decently-shaped trackballs I know about has gone off the market. (They were all wrist-breakers as well, but still better than anything else I ever tried.)
Decent trackballs I have used, in order of decentness:
1: Logitech Trackman Vista. Perfect layout. Very expensive, out of production for quite a few years now. I have worn out about 12 of them, one by one, and there is now just one left. (Sob.) Three buttons is always nice.
2: Microsoft Intellisomethingorother (I mentioned it above). Almost as good, but the right mouse button should be on the right-hand side, not both under the thumb. Hopeless if you are left-handed (which I'm not, but I do use the mouse left-handed from time to time). Only two buttons, but that's OK. Two is enough. Plus it has a scroll wheel, which is great for resizing fonts in Mozilla. Out of production some years ago.
3: Kensington Orbit 3D. A truly stupid idea, a vibrating trackball! It has a tactile buzzer that goes off whenever you do ... er ... something or other I forget. Thankfully, if you don't load the stupid drivers, it works just fine as a standard mouse. Just as well, really, as Kensington's drivers are the most complete and utter pox I have met since the Genius mouse drivers of the mid 1990s. USB only. (Marks off.) No scroll wheel, only two buttons, but it does at least have a good shape and a decent feel. I'm using 3 of them at present as I can't get any more of the Logitech or Microsoft ones. Went out of production as soon as they had made 100,000 and sold 3. Been floating around remainder bins ever since, but they are all gone now.
All three use rollers, not optical and need cleaning regularly. Yuk! But what can you do? No-one makes a decent trackball anymore.
Others I have tried and not liked: the various weirdo red Logitech thumball things. I can tolerate one if I have to (such as when I'm at the Belinda house), but doubt I'd ever really get used to it properly. You just can't do stuff with your thumb the way you can with your fingers - not because thumbs are stupid, thumbs learn to do the fine stuff quite quickly, but because with a real (finger) trackball you do small movements with your finger, larger movements with your wrist, even the elbow. Flick, let the ball spin freely, drop the hand to stop it. Much better than any mouse. (IMHACIUO.)
Kensington ExpertMouse. Too clumsy. And LOUD! I tried and tried to get used to a pair of these, but in the end gave up. The ball is just too big and too heavy. Dumb square shape too, not comfortable.
Various cheap no-name trackballs that are well-shaped and sensibly laid out, but manufactured with all the precision and flair of a gunny sack.
Nobody makes decent pointing devices anymore.
Bring back the Trackman Vista!
