Joe Berry says he wouldn't trade his PDA for anything, except maybe a better model. Joe has run his own company for the last seven years, but he says that his PDA has completely changed his way of working. For example, when he used to go on business trips he had to take lots of things with him like his day book, address book, laptop computer, photocopies, etc., but now he can fit them all in the palm of his hand. "Last week I went to Germany on business for a couple of days, and my suitcase got lost. If that had happened in the old days, I would have had to cancel all my meetings because I wouldn't have had the necessary information. Now I can just get it from my PDA. I can even store presentation on it. It really has changed my life completely, but I'm a little bit nervous about losing or breaking it, so I make sure I still keep a back-up copy on my office PC, just in case something bad happens."
