Ok. I tested (played around with) one:
- It's beautiful!
- It's usefulness is subject to the user's need, comfort, & expectations.
- Its little ball was nicely responsive, handling up/down, left/right, AND diagonal.
- I wanted all the buttons to have more of a "click" feel (but that's ME, doesn't make the mousie wrong.)
- I felt it was very zen: like the mouse & my conscience would have to be in harmony with each other, because it wanted a very sensitive, light touch, & I'm no mongo, I'm a 100 pound girly-girl. (Again, but that's ME, doesn't make the mousie wrong.)
- When going into System Prefs to set the right & left click buttons for your own prefs, it wasn't in System Prefs. I don't know if maybe it wasn't set up 100% yet at the Apple Store (Grove in LA), but it seems like the store would have had their new little gizmo set up 100% for us to demo it. Or maybe its set-up is somewhere other than in SysPrefs. That's a question for the Already Owners to answer.
- All in all, I wanted to buy it for its beauty, but didn't because I realize I just really like my little touch pad on my iBook, regardless of how many times I'm told how much easier Photoshop is with an actual mouse.
- It's going to be great for some people, and not for others. So far I haven't seen one mouse that satisfies every single user.
- That's why they keep trying to build a better mouse (trap).
