A clicky scroll? Whoa, I couldn’t tolerate that. I’ve always held down the middle mouse button to scroll horizontally.
Having to use OSX really threw me off… seriously, who uses the desktop widgets (clock, weather, etc.) that much to justify having a vital mouse button bound to that action in every application?
The mouse I’ve taken a fancy to is Logitech’s G700. It’s wireless, doesn’t need a cradle to charge, and has a ton of programmable buttons. Comfy shape and dual-mode wheel, too! Also, instead of a horizontal scroll functionality, I set the right and left wheel tilt buttons to “play from selection start” and “start/stop” respectively. It’s a good kind of handy.
