I've noticed that most editor's I've worked with tend to use graphics tablets instead of mice for their input device. I would imagine there are many on this forum who do as well. I'm just curious why this is, are they just more comfortable to use, or more accurate or what? I'm considering getting one if they're worth it.

It's just a matter of which tool you're more comfortable with. If you're considering installing a tablet, do some searches on this Forum for Waacom, as there have been conflicts using them, and specific driver versions needed to solve the problem.

I've used graphics tablets for many years and we have several here -- 2 Wacoms, Calcomp large format and Acecat wired...

The Wacom Intuos 4 is excellent. It is indispensible for Photoshop, Painter, etc., and I feel lost without it regardless of the software.

The Wacom Tablet changed the way I interact with the Avid application. For me, it's much faster and intuitive for my hand to simply move right to the spot on the screen I need and click. No more dragging a mouse along. I feel like I'm moving faster and the carple tunnel I was developing has gone away.

Funny...cuz I am always fighting carpel tunnel syndrome when using my Wacom "ergonomic" pen. I have wrapped it with canvas to make it 10 times thicker and that seems to have done the trick.
