While the first credit-card sized PDA, the Rex, is long gone, the idea is still with us, most recently incarnated with Royal's Vista. The problem with the Rex was that you needed a computer to enter your data. Royal has removed that necessity by including a folding keyboard you attach to your Vista.

While I prefer my mini-PDAs to allow input with a stylus, like Oregon Scientific's Echo, people who hate pecking out information on a virtual keyboard will like Vista's input system.
