When I had mine, I was back to my regular duties at Microsoft in 3 weeks. I was up for some special training that would get me a promotion and I would have gone to that if I had to crawl to get there. The original plan was to work a s-load of overtime, then take a few weeks off to recuperate but the plan didn't go exactly that way.
How I typed was with a pencil in my right hand, I would wrap my middle finger around it while otherwise mostly holding a fist. I'd hold the pencil straight up and down and use the eraser to work the keyboard. It's harder to describe than to do but it worked, for me anyway.
That didn't hurt but using a mouse right handed did. I had to use mice at work but I bought a touch pad like laptops have today to use on my desktop PC at home. I got pretty good with it but playing solitaire was kind of complected.
