Common Laptop/Netbook Positions to Avoid

I love laptops. I’ve been using them for years. The great thing about laptops (and netbooks too for that matter) is that you can use them
just about anywhere. The downside: If you spend a lot of time in the wrong
position, you’re in for a world of RSI pain.
The
illustration above—from weblog Core77′s netbook case
study—highlights ten common usage positions and the pain points
you’re asking for down the road with each. (No one wants glowing red
joints!) Interestingly, the most comfortable position, according to the
study, is position #2 above: lying down with the device slightly elevated on the user’s thigh with bent knees.
