Attention all IR mouse users: ditch the dongle and get a bluetooth mouse
I really like my Dell bluetooth travel mouse. No messing with the dongle, just turn it on and go.
I've got the Dell 5-Button Bluetooth Travel Mouse, and it works great. I like the combination of buttons, which I understand are even programmable. The track wheel is the feature I use the most though. (It makes quickly scrolling through all of those really long Plone css files a breeze.)
