The Edgewing is a little hunk of plastic that sticks to your desk and offers a bit of wrist support for heavy mousing. While it is niether amazing or super cool, it actually works. I slapped one to my desk today and it's quite comfortable. You can buy one or two or get them with your business logo on there for giveaways. $9.95 each, but your carpal tunnels might thank you.
