I've talked a bit about ergonomics before. I use Colemak as my keyboard layout, but I learn more and more that layouts aren't as important to speed and maybe not so much to ergonomics (but I'm not going back to QWERTY ever because it is the pits.) I use a Microsoft Natural Elite as my keyboard and have for a few years. I expect to use it for years to come, because I've started to collect them. Goodwill is a magnet for old keyboards.
Escapism is often at the heart of gaming. Despite what anyone's heard, gamers don't want to violently murder everyone in the middle east. Gamers are more passionate and intelligent than what their own words may display. In the real world, learning how to fire a gun, sprint for long periods with 100 pounds of gear, or impossibly climb tall buildings is incredibly hard and, while they can be somewhat esoteric, video games enable anyone to do those things despite their lack of ability.
