I’m not sure there’s anything ergonomic about the Air-Flo Mouse, but when I saw the news heading, I had to check it out. (Judging by some of the reviews I found, it’s been out for a while, so I’m not sure why it showed up in my news… but hey, I thought I’d share it anyway). The Air-Flo uses a “patented air cooling technology” to keep your hands dry while you’re rigorously working (or gaming) at the computer. It has the usual better-than-what-came-with-the-system perks and a couple additions: air vents, scroll wheel, optical sensors, and rubber gribs. The mouse retails for about $20.
