Matsucom has decided to call it quits and stop producing the PDA device, which managed to incorporate a full set of PDA functions into a fairly ugly watch. The OnHand was hobbled not just by a laissez-faire approach to marketing and a poor design, but by its use of proprietary technology and limited PC support (despite being introduced in 2003, it used a serial cable instead of USB). The small OnHand community did come up with some decent hacks, including a GPS hookup and an external keyboard, but that wasn't enough to keep this going. If you're still dying to get a wrist PDA, though, all hope isn't lost. Despite constant rumors of its death, Fossil's Palm-based Abacus wrist PDA is still available from TigerDirect for about $50.
