We mentioned the Leapfrog FLY Pentop Computer before, but this time, it's finally hit shelves. As we mentioned, this is a computer built inside a special pen "computer", and works with specially made paper. For example, you've got some crazy calculator function: you draw some numbers on the paper, a plus sign, and an equal sign. Then you simply tap a number, and it'll say the number out loud. Tap 2, the plus sign, and 4, and the equal sign, and the pen will yell out 6. This also works if you draw out a musical keyboard; it'll play out a tune depending on which notes you tap. I didn't believe the hype until I actually saw a demo of this first-hand — the technology blew me away.
