The "How to Mouse Goofy" article on Life Hacker is the reason behind this post. To leave a comment on their site – you need an invitation like gmail or from another person who'd been signed up etc. etc. etc. And though i'm a regular LifeHacker feed subscriber and find their articles interesting, this was too much trouble. Not for a simple thing like leaving a comment. I'd rather do it here with no additional hoops or loops.
I've been a Computer and now an Internet addict for more years than I can remember. The usage levels have kept going up as the content on the web has. I found myself straining my wrist. I must confess some of it was because of the games ( Wolfenstein 3D, Snood, Aperion – yes, I'm that old 
) that i was playing on the computer.
About 4 years ago it got pretty bad and I decided to do something about it. I had already tried the optical mouse and then the optical cum wireless mouse. None of those really helped. Then I got myself a Wacom tablet with the idea of learning to do digital art. I ended up using it as a mouse replacement and it really helps. I've used the option where the tablet maps the monitor screen so every spot you tap on the tablet is linked to a spot on the monitor. No more rushing around with the mouse or your finger on a trackpad. No more wrist strain.
I'm now looking forward to doing more with it than just mousing around.
