Rating: - I like this mouse.
I am very happy with this mouse for my desktop. With this mouse, I have no need for a mousepad.
Rating: - excellent wireless mouse for my Mac
I use this with a Mac Pro running Leopard (10.5) and have no serious complaints. Tracking and scrolling are great. It's very comfortable to use and has the right number of well-placed buttons for an experienced user. It connects quickly and reliably. I replaced the original rechargeable AA battery with a new one from Sony and get about a week of moderate use per charge, which works well for me.
Rating: - A comfortable and high precision mouse
A comfortable and high precision mouse, the bluetooth connection seamlessly paired with Windows Vista. The battery lasts long, even though I constantly forget to turn it off using the on/off button when not using.
The clickless scroll may be a bit annoying sometimes, but it is very comfort in general use. It is simmetrical, and works for both left and right handed, making one of the extra buttons a bit hard to click.
Rating: - kinda sucky for work involving fine movements
I've had this mouse for a while now and it's always had charging problems- mostly when I run it down to where the red light starts to blink then I put it on the charger and it starts out ok, but after a few seconds it goes to the rapid-red blinking of "charging error". Which is annoying, but if you pick it up and drop it on the cradle a few times eventually it gets the idea.
But lately I've been needing to do a lot of fine mousing, and what I'm finding is that it is constantly going to sleep and missing my fine movements. If you're moving the mouse in big happy gestures it works great, but if you're moving slowly to get pixel to pixel accuracy it just stops responding.
So beware, if your work or play involves fine mouse movement the standard optical mice (like the intellimouse) are much better.
Rating: - Not for me
As reported by many others, the side buttons are hard to reach and the scroller button is nearly impossible to use. So if you are buying for these features, I wold look for something else.
The big problem that made me return it was that sometimes it would not wake my PC from sleep mode (I had to use the keyboard as a wakeup call). When this would happen, the mouse would be dead until I restarted the PC.
This was true even after I updated the software to version 6.2 (the latest on Microsoft's site).
