Most people will think this is a minimouse, but not at all, this is a small big-mouse or a big mini-mouse, i have big hands so i can't handle a minimouse with ease, this mouse feals just right in your hand, if you're right handed the thumb-button is just in the right position, but i find that the zoom function is not for me, i have it as a close application button.
With the intellipoint software (required to install) you can map a specific function for each button for a given application, which i find very usefull, for example, in a drawing app, i prefer to use the thum button as pan, and the middle for pen-styles.
The 1/2 star i took from the 5 stars is because for the click wheel you have to press with more pressure than the rest, and for the wheel not having the stepping sensation you just might scroll right before you click.
Because the middle button is that hard to press, you just might ending tilting the wheel before you actualy press the button (i have 4 days with the mouse and that doesn't happen anymore, but was anoying in the begining)
* Great size
* 1000 dpi !!!!!!!!!
* Looks sharp
* 4 way tilt wheel
* Rubber sides with grips
* Nice USB Adaptor (it doesn't count, but it's nice
* No clicks for wheel, it's smooth (but still ok)
* Middle button hard to press at the begining.
* Not-so-good price at the moment (but worth it)
