Magic Mouse Review
The only reasons you shouldn’t get this mouse are if you are prone to hand camps or other hand and joint issues and/or you need auxiliary buttons for certain apps (usually CAD people like to have a middle click).
This is a great, simple mouse. Left Click and Right Click. Fantastic scrolling (Apple really knows how to do momentum scrolling right, after using the Wacom Bamboo touch I know that there is a right and a wrong way). Back and forward are a little awkward and they don’t work everywhere (I thought I would be able to use them for changing songs in iTunes).
Apple could do a lot this mouse in software. If they wanted to add a third button they could make a gesture where you tap the edges with both fingers or double tap in the middle of the mouse. It would be a shame if they just let it as is.
