Next-gen Apple mouse all touchy feely

Looks like the next iteration of Apple’s mouse will be a departure from how the current Mighty Mouse works. This new design method is capable of switching between operation modes solely based on the way a user holds the mouse’s enclosures. This means a different hand position will result in different operations, but would this pose a problem to the older folk who will definitely take some time getting used to the various positions? The new mouse will also come with one or more concealed buttons just like the current Mighty Mouse.
