Logitech MX Revolution - especially since a
Bluetooth version hit the FCC recently.
I used the Mighty Mouse that came with my iMac for about 3 months. While it's not the worst mouse I've used, it's certainly not the best. I had to send off for a replacement within a month since the scroll ball got jammed up and the replacement has a broken scroll ball. The buttons on the side are quite easy to press accidentally and it gets dirty FAST since it's made out of plastic... and the right click/primary click system is easy to go wrong since it's touch sensitive.
I recently bought a Logitech MX Revolution from Amazon (it was cheaper) and I loved it... but unfortunately it was a faulty model. (My friend bought one from the same company that was selling through Amazon and his broke, too)
Really, I would buy that mouse if you're going to buy any - especially with the Bluetooth version on the horizon.
If Amazon gives me a refund (Which I hope it will do), I am certainly buying that one over the RF one. Works amazingly well with Leopard (Since you have spaces to control, too!
😀) and you can assign the buttons to do different things in different applications - which is great! (like, I set the buttons on the side to change between the Arrow tool and brush tool in Photoshop, and set the "search" tool (Although I used it primarily for Dashboard) to capture a frame in iStopmotion). So yeah, great mouse! If you're going to buy any mouse buy the MX Revolution - especially since it's rechargeable and not battery (thus you help save the environment and save yourself some money in the long run).
That said, the MightyMouse is the best Throw-in mouse I've ever seen, but it's definitely not worth the money, effort and frustration to buy it separately.
