OnHand PC

The OnHandPC has the power and memory of a Palm m100 in the size of a wrist watch.  Batteries last up to several months which is pretty good compared to other devices like a Palm.  The OnHand PC uses 2 lithium batteries which are actually really cheap.  Replacement of these batteries can be done without loosing any information.  A handy joystick will help you navigate applications.  If you are a programmer, you can even develop your own applications in C.  

With a docking station or IR connection, you can transfer data from your watch to your pc, or pc to your watch (yes you can also transfer data from your OnHand to another OnHand through Infra-Red). 

The onHand PC provides all the popular features of palm-type pda devices at a fraction of the size. With onHand PC you can view your to-do list, add appointments to the calendar, look up an address, balance your checkbook, or simply relax and play games. 

Oh yes, you can also use it to tell time... imagine that!

How can data be entered on a OnHandPC?  The easiest way to enter data is by using your computer and transfer the data as explained above.  However, with the help of the tiny joystick located on the bottom of your watch, you are also able to type short messages.  An on-screen keyboard (alpha-numeric, numeric, or by using word templates) is used to enter information as you can see in the picture below.

Numeric Entry

Word Template Entry

To be honest, entering data like phone numbers or a short note is absolutely no problem and goes really fast, but once you decide to actually write a story, you might want to consider using your PC and transfer the date to your watch.  Many people prefer to use the companion link software which allows you to synchronize with your favorite organization software like Microsoft Outlook, Symantic ACT, Goldmine, Microsoft Schedule+, Lotus Organizer and 3Com Palm Desktop.  Several programs for your PC are included on the CD to help you enter data more quickly.
