Data is never far from your reach. Graffiti is the handwriting system used by the Palm OS for data input. While this is not true handwriting-recognition, it is highly accurate and relatively fast. Characters are input via the lower portion of the screen with separate areas for letters and numbers. Virtually all characters are represented by single strokes closely resembling standard, upper-case printed characters.
Punctuation is input on the same screen area with a dot preceding the single stroke character.
Because of the close similarity of Graffiti letters with standard print, the Graffiti system is easily learned and mastered. If you don't master the Graffiti character set, there is no cause for worry, because a pop-up keyboard is always avaliable. Note however, that Graffiti is still not as fast as handwriting on paper or keyboard input, thus making the Palm computer primarily suited to be a data-retrieval device. It really depends on what you'll be using it for. Many people don't know what they'll end up using their Palm device for, and that's entirely okay, but some initial planning can save you some money in the future if you need to upgrade.
