Multi-funciton Pen

Normally, I'm not all about things that do everything--I don't need a phone that's also a shoe horn, but this is interesting. The multi-function pen features a ballpoint pen, a highlighter, a lead pencil, a stylus for PDAs and a ruler with centimeters and inches. Sounds like an engineer's wet-dream, but I know there's been times when I needed to measure something that was 3mm long and I had to waste time going to search for some calipers or an unweildy ruler.
