Have repetitive stress injuries and carpal tunnel syndrome left you curled up on the floor in pain like a sad little shrimp? Geoff Hart knows computers and knows how you can prevent them from hurting you:

If, like me, you've replaced your desktop computer with a laptop, you've probably noticed that laptop keyboards are ergonomic disasters even by the standards of traditional desktop keyboards.

If you plan to use your laptop at a desk, consider buying a good external keyboard and use that instead.
