Ok, so after having used it for about a month now, I can deliver my final opinion on the Mighty Mouse.
Using the scrollball is now 2nd nature to me and doesn't annoy me with its sound, there aren't any weird vibrations either. In short - it's perfect.
I wouldn't recommend the Mighty Mouse for FPS's or even WoW. I've been using it for both and the inability to hold Left click down and then hit right click is really quite painful. Particularly as I used to do this in WoW, to trigger forwards motion in PvP when using my left hand to cast a spell which would require me to move my attention away from WASD motion controls. At the moment the side buttons trigger auto walk, however that's a click on/off feature as opposed to 'both mouse buttons held down' which made you run forward as long as you held them down. This makes it considerably harder to control your character in PvP.
At least the mouseball still functions as a middle-button press. This is set to my old default of Flash Heal (trust me, after the amount of time I spent in Molten Core I can't imagine putting the keybind for that spell anywhere other than on the mouse)
However, to replace my previous black marks against it, the Mighty Mouse has now developed a squeak.
I think I've dealt with it by stretching the plastic shell using my fingers a little, just to give it some more room but if the internet is anything to go by this is a fairly common fault which has surfaced around about this time for most users (ie, after about a month's use).
Let's hope it doesn't come back
(Edit: Ooh Brain wave.. Perhaps I can use Middle Click as a 'forward' trigger and bind Flash Heal to the side buttons, after all that only needs a single button press rather than to be held down)
Later
John
