Finally, a worthy mouse!
After using the old Microsoft Intellimouse mice for years no other mouse ever seemed as good. I tried a number of Logitech and other Microsoft mice but they always had small side buttons, a crappy scrollwheel, or were pathetically small. Unfortunately, the newer versions of the Intellimouse have poor reviews and strange ergonomics.
Last weekend I picked up the new(ish) Microsoft Habu mouse at Fry's and was back again today buying a second one for my desktop at home. The design is very similar to the Intellimouse v2 and it looks great. It costs $60, but even if it lasts for half the 7 years that my old Intellimouse did I'll consider it money well spent.
