I've looked at the T3 in a few different retail stores. One of them had a graffiti area with 3 distinct writing spaces (one for lowercase letters, one for uppercase letters, and one for numbers). Another had just 2 (letters, numbers) with various icons/shortcuts on either side of the two writing spaces.
Is it possible to switch between those two layouts, and if so, how easy is it?
Also, I've heard some stuff about "graffiti 1" and "graffiti 2" .... what is the difference? Will I have to learn a whole new system of graffiti if I upgrade from my current M130 to a T3?
The T3 offers 3 input schemes for the Dynamic Input Area (DIA): The old standard graffiti silkskin, a 3-paned silkscreen w/no icons (called "wide" in Palm literature), and the qwerty keyboard. They can be selected by tapping and holding on the far right icon on the status bar at the bottom of the screen.
Graffiti 1 allowed entry of all letters and numbers with one stroke--you never have to lift the stylus during contruction of a letter. That required some learning of special strokes for what are multiple-stroke letters in the language. Graffiti 2 went to a more "natural" 2-stroke arrangement for many characters like 't', 'i', 'k', etc. G2 is in fact a liscensed version of CIC's Jot. Once you learn anything, switching to something else requires some effort. I used Jot under G1 anyway, so the move wasn't particularly difficult for me. Other people who were very proficient at G1 hate G2.
