A long and
rambling response...
I had a
Microsoft Wireless Notebook Presenter Mouse 8000. It was portable, Bluetooth, and had a few extra buttons. It comes with a bluetooth dongle, but in one of the early Leopard updates, Apple added support for connecting to this mouse without a dongle. This was the reason I got it.
I used it for a few months, and it was generally great, but just today I finally grew tired of the occasional random disconnects I was having on my MBP, where the mouse would stop working for 5-10 seconds two or three times a day. I've now had this problem with several 3rd-party bluetooth notebook mice now, on both my PB and MBP. So I went for a non-BT mouse today.
Anyway, my replacement was going to be the relatively new
MS Wireless Laser 7000, basically because it's *not* bluetooth (jumping ship for reliability), it's full size, and I *really* like the chrome-on-black aesthetic.
...but, I ended up getting the Logitech MX Revolution due to it's multitudinous functions and nearly universal acclaim among PC and Mac users (via SteerMouse -- NOT Logitech's drivers).
And I'm very happy. This mouse is awesome.
(Footnote: If anyone else wants to try to get the MS 8000 mouse to work more reliably, or if you don't mind using the dongle --- which indeed works reliably --- the mouse is for sale in great condition. Say $40 + shipping... half off retail).
