Computers go from filling a Room, to filling a Desk, to filling a Lap, to filling a Palm, to filling a Pen?

This looks very interesting.

How times have changed. Back when I was growing up in the late 70s and 80s, lots of parents thought Scrabble was all the stimulation children needed to excel in school. Nowadays, adults worry that their kids won't do well unless they own a laptop, a cell phone, and a personal digital assistant (PDA). And soon, perhaps, the Fly pentop computer will be added to that list...Developed by LeapFrog Enterprises, a maker of educational toys, the gadget is just what it sounds like: a talking computer hidden within a pen the size of an electric toothbrush.

Not sure how practical this thing is, but it has the feel of something that will have more use as it grows and matures. As someone once said, "What use is a newborn baby?"
