I know that the Mighty Mouse is a "You either love it or you hate it" situation, so let's finally get a clear view of the public's view of the Apple MM. Me? I hated it, here's why: 1. Both side buttons act as a single button, they can not be set as alternate controls. 2. The 360 wheel feels extremely cheap and constantly gets stuck/doesn't respond (This is not a defect, it happened with a few I tested out in the store, I figured it was just from all the wear and tear) 3. You can't right click without lifting your left finger off the mouse. 4. The side buttons are, for some odd reason, pressure sensitive instead of "clickable" buttons, making them easy to set off. Very unintuitive and useless. 5. Terrible tracking. The slightest bump in the tracking surface and the mouse would go flying. (I had the corded Optical version) 6. The noise when clicking is incredibly loud compared to your average mouse. 7. The amount of travel needed to click. 8. It's uncomfortable. If you're one who likes resting your palm on the mouse, it's not for you. If you just use your finger tips, it's OK.
