Laini and I went to an [Apple Store](http://www.apple.com/retail/menlopark/week/20050807.html) yesterday. While Laini played on one of the kids’ eMacs, I checked out the new [Mighty Mouse](http://www.apple.com/mightymouse/design.html). I walked out of the store with no desire to buy one (or two). For the past couple of years I’ve been using [Logitech MX310](http://www.logitech.com/index.cfm/products/details/US/EN,CRID=2142,CONTENTID=6952) mice. I have two, one for my G5 and one for my Inspiron. It’s confusing enough that I have to remember the changes in the keyboard configuration (control vs. command) when I move from one computer to the other, at least I have the mice configured exactly the same and they feel the same.
I like the way the Logitech feels under my hand. It’s symmetrical (important for us southpaws) and the part that is under the palm is higher than the part that is under the fingers. Your tendency is to rest your palm on whatever is underneath it, even though ergonomic experts advise you to keep your wrists up while mousing and keyboarding. Apple mice don’t lean forward like this so you either damage your wrist by letting it rest or you have to be mindful of keeping your wrist elevated. Yeah, the Mighty Mouse is sleek looking but I think it would be very uncomfortable for long term use. I had nerve surgery on my wrist in 1989, so I am very sensitive to mouse ergonomics. If I’m not using the right mouse for my hand, I feel it. Fast.
More than the ergonomics, I was disappointed in the general feel of this mouse. I expected it to have more weight and presence than it did. It felt like a cheap $19.95 mouse. Very light, almost too light. If I saw it sitting on a shelf in CompUSA I would think it was a no-name brand. The little ball felt flimsy. I think I would miss the solid click I feel when I scroll my Logitech mouse one notch. The squeeze-gives-you-dashboard thing is nice, but couldn’t you do that with any programmable mouse? Side scrolling is cool, but I don’t do it often enough with 1920×1200 resolution to be worth it.
