Okay, anyone who can help me with this, great. Post here and let's make this happen. I want to put together somebody who can design a dry box that can fit most PDA's, with my guys who can write a cool dive deco program in windows ce, so users can have a cheap dive computer in the form of an inexpensive piece of software that works with their existing palm top, that can be upgraded easily and inexpensively. Thanks for any help anyone out there can offer. Dive manufacturers, you are invited to help, too.
