The side squeeze buttons need some time to get used to. Mine were stiff but now they're fine. I really had a huge problem with the MX Revolution. My hand was getting sore after trying it at the store for about 5 minutes. IMHO, the Mighty Mouse has a better shape. It's like a bar of soap. And I don't know about you, but I use soap bars every day when I shower so the shape is natural to me.

Yeah but do you shower for 8 hours a day? That's the problem for me anyway - long sessions with the Mighty Mouse start to hurt my hand.
 
I stopped using my MightyMouse when the scroll ball stopped working. Every person I know that uses the Mighty Mouse has had the same exact problem... you can scroll up on a dime, but scrolling down? Forget about it.

I now use the Targus wireless mouse with optical scroll pad. It's well worth the price and it doesn't give you hand fatigue.
 
Lemme know the address of your local hospital so I can send you flowers and a card this time next year after you've had your wrist surgery.
I've been using them for a few years and I spend 14hrs a day working with them, no issues for me apart from the occasional dirty scroll ball but a damp cloth cures that easy enough.
