The concept of holding the whole world in your hand takes on a new meaning with the red Fly pen exclusively from Target. This quasi computer-in-a-pen concept is being marketed towards ages 8 and up. The fly pen has a built in processor that scans in what you write on special "FLY" paper, computes math problems, has the ability to record voices to remind you of appointments, and it allows you to draw musical instruments which you can then play and record the instruments.  Keep in mind that all of these magical features will only work on the Fly paper sold specifically for the Fly pen.  To get you started the Red Fly pen comes with 35 sheets of fly paper, 17 games, ear buds and a carrying case, whichall together retails for $99.
