I haven't used a mouse since about 1999 when my index finger told me I'd been doing entirely too much double-clicking in my Flash animation job. It's been all drawing tablets since then. I have a mouse that I use on the rare occasion of playing a game that requires you to move the view by pushing the cursor against the screen edges; I have to hold it in a weird, awkward grip because that tendon still starts screaming if I try to use it to click a mouse button.

I'm in much the same boat. Daily Apple trackpad driver for the past 15 years at least, maybe more. Every time I have to use a PC with a mouse it kills me a little (and don't get me started on those trackpads cheap PC laptops ship with...)

I switched to a mac trackpad years ago due to hand pain that comes whenever I grip/use a mouse. Something about that half-closed-hand light grip has become just super painful. Unfortunately I still need to use one for FPS gaming, just haven't found a controller to match the speed and precision needed to aim and fire at a game opponent.

I like laptop trackpads because it means you're always close to the keyboard, so you can easily switch between cursor and typing without only relying on one. It's good for UI design work for example.

Trackball gang here. Nulea seems to be my latest iteration, I've tried a bunch of them.

When I first learned of them I thought they were ridiculous, but it really saved my hands going ergonomic w/ the Trackball and Keyboard (Microsoft Ergo style - Nulea as well).

One of my favourite features on my Asus Zenbook (Windows) is the "Disable Touchpad" hotkey.

I can't use the trackpad for too long without getting RSI type feelings.. I am trackball these days.

I get the love for Macbook trackpads, but Lenovo really nailed it with the ThinkPad trackpoint and glass trackpad combo, especially on more recent models.

Windows has something better than three finger drag. It has single finger second tap and hold. Plus extended zones for when the trackpad is not big enough to stretch across

I love the Magic Trackpad and I've used exclusively for years, at some point my wrists start to hurt and I'm now stuck with some Logitech MX Vertical.
