Whack that ball by remote with the Playmate PC

The Playmate PC takes a state-of-the-art ball machine and merges it with a wireless-enabled, ruggedized PocketPC to create a custom training system for tennis fans. Save drills, program shots,
access preprogrammed teaching drills or send dozens of balls flying rapidly at astonished tennis students while you sit by and chortle in amusement. Priced for pros and trainers (or amateurs who have already spent way more building their own court) at $7,995.
