Exhibit A: The new mac keyboards. Unlike every non-musical keyboard I've seen to date, new mac keyboards such as the one in my MacBook have perfectly flat keys and a much shallower action than traditional keyboards. Experience has shown that my hands suffer using this keyboard compared with my cheap and nasty USB PC model, particularly when gaming.

I have a theory that touch-typists like me like to use the traditional shallow curve in the top of keys to keep our fingers in place. For normal typing of any text where you're centred around the home keys this isn't a big deal because you can subconsciously align yourself on the dimples on F and J every time your index fingers stray that way.

If you're playing a game where your left hand is shifted one key to the left, for WSAD or something similar, you don't have such an easy way to tell when you're in the centre. I find myself frequently sliding my fingers around in little circles feeling out the edges of the keys so that I can stay squarely in the centre. This isn't an action particularly easy on the muscles and the result is RSI.

So what conclusions can we draw from this?

• Pay some attention to what you fingers are doing. It could be that they're not comfortable and you're subconsciously making do with something you shouldn't.
• Apple should stop making dumb keyboards.
• Gaming on a mac? lolol you are kidding right?!1!
