My Logitech mouse starting acting up on me the other day (Logitechs have a way of doing that!), so I started thinking about replacing it and decided on the Apple Magic Mouse. UPS delivered it yesterday and I started using it immediately. But oh, what a disappointment! It’s an ergonomical nightmare, being much too shallow for my hand. The tracking leaves quite a bit to be desired. Downloading and installing the free Magic Prefs certainly helped speed things up and give more control, but at the end of the day, I found it pretty much unusable for the kind of work I do. So today, after having the thing in my possession for just over 24 hours, I packaged it up and sent it back to Amazon and ordered a Logitech Performance Mouse MX instead. I’ve read great things about it and am hoping it will be a good purchase. A three year warranty helped clinch the deal. It should be here tomorrow thanks to Amazon Prime shipping.
