Despite seeing the pen at CeBIT in 2006, CES was the first we've heard from Wowpen in nearly a year. The pen looks like a pen, but works like a mouse with either PCs or Macs.
There's even a built-in laser pointer, optional flash memory, and "silver nano" technology to keep germs away. If you've been looking forward to the Wowpen, you can pick one up for $49. It's nice when something cool turns out to not be vaporware.
