A few thoughts: One of the designers at my place of employment used a thumb ball from Logitech, and swore by it, but one time I attempted to modify a small part of a drawing using that thumb-ball, and it drove me crazy!
i would say that that is one of the reasons that mouse movement should always be in a feature in a readily accessible configuration, so one can change parameters as needed. it would be great if there were 2 selectable settings, fast/slow. even better, if there where 3 or 4 preset setups, fast, slow, between. when i am using mouse for reading, writing, web browsing, i like fast acceleration and threshold. for cad/eda, i like slow acceleration and threshold. such could very easily be selected by pressing middle button and left button simultaneously for stepping up. pressing middle button and right button simultaneously for stepping down. or, pressing middle button and left/right button would present a menu at current pointer position to select a preset config and a choice for a config window. i had considered doing such, but i am an al programmer and i admit to being 'weak' with c/c++, so i never took it further than just thinking about it. with linux being primarily c/c++, if i ever find time, i may give it a go. tho it would be better if you are, or a reader who is, heavy into c/c++ would work up routine needed, it would be a truly needed winner.

But if you're into thumb-balls,
having started with a thumb ball, i have formed an 'addiction' for it. ;=) as such, i have learned to use it as a finger ball. to be more accurate, a thumb and first finger. it allows me to have a finer control over pointer movement. > it looks to me like the wireless unit pictured on the left is a thumb-ball. this is true.
One other thing: I suspect that like the Kensington, the Logitech ball is not captured, and will fall out if you upset the base.
this is also true. original has a retaining ring with a recessed hole so it can be rotated for removal to remove the ball for cleaning. there where complaints about this, so, i believe, to also cut manufacturing cost, and make cleaning easier. and they _do_ need cleaning of motion detecting window and ball contact points. i am sure kensington is same way. when you consider all the advantages of a marble, a little cleaning is no big issue. at least not as i see it.
Here's the Kensington link:
after watching the dumb video, i recall why i prefer the logitech. you can rest your hand on the logitech. not so with the kengsington. returning from kengsington site and noticing scroll bar gray area, i believe i need to bring this 'book' to a close.
