Got Mine...
My Mighty Mouse was delivered today.
I like it. It's exactly what I expected it would be -- which is a standard Apple Mouse with extra, albeit
differently executed, functionality. Some of the comments in the online reviews I've read are good observations, others are overly picky. Basically if you like the standard Apple Mouse, you'll probably like Mighty Mouse. If you don't like the standard mouse to begin with, Mighty Mouse ain't gonna win you over.
Overall it's so close in form, if not identical, to the standard Apple Mouse that if you don't actually look at it, and unless your finger hits the scroll ball, you don't know this is a different model. I've seen some reviews say it's lighter than the standard mouse, but to me the weight and hand-feel is pretty well identical. To me, cursor movement & accuracy is identical to the standard mouse as well.
Under Panther you get non-configurable left/right clicking and scrolling, while some Exposé features can be set using the Exposé pref pane. I guess I'm buying Tiger next, which will enable full Mighty Mouse configurability (among other things heh heh). In any case I have absolutely no problems with left/right clicking -- for me it works reliably, without confusion. The scroll ball will take some getting used to because it is small however it does work as advertised. The scroll ball is definitely less annoying than the clicky/crotchety scroll wheel on the cheapo mouse they gave me to go with my WinXP box at work. A couple of pics are posted
here.
