Once upon a time there were these places called “retail stores” where you could go look at actual products and even try them out before buying them.
Alas.
Alas.
How long does it take to decide whether you love or hate a thumb-ball? A big ball? A SpaceMouse? Has anyone who didn't use a ThinkPad decide to buy a keyboard with an integrated nubbin?
Sure, I can buy twenty devices for $200 each and return 19 of them. That puts 19 items into "open box" status, causes me to re-pack and re-ship and track 19 items, and makes 19 vendors vaguely cranky at me.
In the end the problem was actually moving the hand away from the keyboard, so no tilted mouse, thumb mouse or track pad worked. A RollerMouse saved me. I even game with it now, heh.
Just lucky my company paid for all of it (and the ones I didn't use they got back by me distributing to others within the company with issues)
