I searched the Forums and didn't find anything directly on point, so here it goes... Does anyone have experience with Bluetooth mice beyond the Apple Wireless Mouse? I got an Apple Wireless Mouse last week and have been somewhat disappointed in its smoothness / responsiveness / precision compared to my wired Microsoft Intellimouse. The best way I can describe it is that it is like using one of those old roller-ball mice. I was just curious whether anyone tried other Bluetooth mice and whether they were an improvement from the Apple offering. Thanks.
