Leah, funny you should mention the folding keyboard. Before there was any such thing, a colleague was showing off his new electronic organizer (this was pre-pda) and bemoaning the fact that the keys were so small he found it hard to type on it with his large hands. I told him what he needed was a normal size keyboard that he could fold up and put in his pocket with the organizer - of course he laughed me out of his office and (succeeded) in humiliating me as he laughingly described Margaret's ridiculous invention to whoever would listen. When I first saw the folding keyboards on the shelf at Staples, I wanted to hit someone
Ed, I'm just starting the process, but will try to keep you posted.
Since I started this thread, I've been in contact with one person who is wildly excited by my invention, and another who suggested that since it's so simple that anyone could do it, I should just give away the instructions.
I still remember the feeling I got seeing folding keyboards (not that I had the expertise to actually design one anyway

) and I don't want to give up on this one.
Take care, Margaret
