I've been looking to buy one, but I don't find them in any of the familiar places.
Not in the computer stores or Best-Buy or Wal-Mart.
Seem, to only be, available on-line? I guess, I'll have to "order" one.
Office Deport had one 'in-stock'
Well, I bought a TrackMan Marble (rollerball mouse) by Logitech.
Bought this model > http://www.officedepot.com/a/products/8 ... se-Silver/
Connects well and everything worked 'outta da box' Although, they recommended installing the Logitech drivers via Windows. (I don't have any Windows)Large trackball reduces hand and wrist motion
Easy-to-use trackball makes navigating easy and comfortable. Whether you're concerned about comfort, limited space or both, this corded trackball is a convenient, stationary alternative to a standard mouse.
Optical technology delivers smooth, precise tracking.
Sleek, stylish and designed for either hand.
All 4 buttons work, and the "big red marble" rolls smoothly.
As for speed and precision of the cursor ... very fast and more precise than anything I've ever used.
Not having a 'Scroll-wheel' is a little 'unnerving' though.
We (humans) are creatures of habit.
