I'll stick with my black Apple Pro Mouse, I don't mind having hit control for right click, for my laptop I use a silver MS 'Notebook' optical mouse.
The Apple Pro Mouse is just nice, adjustable click resistance, solid and it just works. I cannot say the same for the Mighty Mouse which is just to me, abhorrent. Hate the thing. It is to my mind a clear example of Apple's ego getting in the way, where they are still stuck up on the hill refusing to acknowledge two button mice at very least are better if you design them in a more conventional manner, rather than a hybrid single button looking thing that clearly shows someone just cannot swallow their pride. Get over it Apple, and design something that puts function over form, especially when it comes to a mouse!
It's a shame as the white Apple keyboard is actually very nice to type on. Certainly One of the best keyboards I have had the pleasure of typing on.
