I just wonder how the forthcoming Mac Voodoo5 card from 3dfx Interactive would fare in such a trial. The Mac was also downgraded for its circular mouse. Let's see how it does, however, when Apple finally delivers a multiprocessor version, or faster G4 chips become available. In August, the iMac will reach the ripe old age of two. To say the round mouse is an acquired taste is an understatement.
Some folks never acquire the taste.
Worse, the design has migrated to the desktop Macs. Just the other day, one of my clients set up a PowerMac G4. Comfort issues aside, just keeping the mouse pointed upward is a constant process of twirling, thus increasing one's efforts even at doing simple mouse functions. This design is a clear case of form not following function. Apple has been universally praised for its extraordinary industrial designs.
