Comment External input devices! (Score 1) 178
As someone who has suffered from chronic RSI for years, your best bet is an external input device.
You can alternate between a mouse, and some of the other options out there. When I'm on the road, I've found the ozupad to be a decent alternative option.

Between a tracpad, a mouse, and an ozupad, you can change things up enough to hopefully avoid the worst of the repetitive motions.
