Apple's new mouse
is funny. To finally release a multi-button and/or wheel-mouse at this point would just be an embarrassment, as every other mouse manufacturer in the universe has had multi-button wheel mice in production for years, and most of 'em work fine on Macs.
So what do they do to one-up the competition? They release a mouse with a little trackball on it!
Honestly. How close are we to having a mouse that comes with a little mouse on top of it? And how long before that little mouse has its own scroll-wheel?
