Over the years I’ve used a lot of different computer mice. Off the top of my head…
- Original Macintosh mouse
- Mac LC mouse
- Original PowerMac mouse
- Kensington Mouse-in-a-Box (I had the beige one)
- Microsoft Intellimouse
- iMac Round Mouse
- Apple Pro Mouse
- Kensington Mouse-in-a-Box Optical Pro
- Logitech Cordless Comfort Mouse (I had the flat keyboard though)
- Kensington Pocket Mouse Pro Wireless
- Kensington PilotMouse Optical Wireless (Special Edition Midnight Metallic)
I’ve probably spent the most time with the original Kensington Mouse-in-a-Box (back in the ADB days), the Logitech Cordless (on a PC at work), and the Kensington Mouse-in-a-Box Optical Pro. Ergonomics and feel are important to me and I think the original Kensington MiaB probably had the best feel of any mouse I’ve ever used. The high back end encouraged your wrist to stay high the way it is supposed to (think 
piano posture 
I’ve never been a fan of the newer Microsoft mice because they promote a tilting up of your wrist with the front of the mouse higher than the back. This can cause strain and RSI – things I’m happy to avoid if possible.
Last week, I replaced the Kensington MiaB Optical Pro (which I’d had for several years on my home system) with the Kensington PilotMouse Optical Wireless. I miss the thumb button a little1, but overall I’m pleased I made the switch. The overall shape of the mouse isn’t as good as the original MiaB, but it’s better than those I tried from Logitech and Microsoft.
The feature I like best are the ribbed rubber sidewalls. With many mice, the oils from your hand will build up on the mouse over time causing a slick feeling in certain areas (like where the thumb rests); the ribbed rubber sidewalls appear to prevent this entirely.
What was/is your favorite mouse?
- I had the thumb button set up to Cmd-Click, I have the scroll wheel button set up to double click. [up]
