I had an old blog posting somewhere here about my Treo on what I liked and what I do not like.
The PalmOne Treo 600 has no Graffiti. Graffiti, aside from what it really means, this is also the name of the writing system software in most Palm PDAs. You learn how to write their way to digitally input real text that can be editable. It is somewhat like a character recognition software to converts what you write into real font letters but you have to follow their proper way of writing.
Being a Palm m100, Palm xeIII, Palm Zire 71 user… the graffiti system was into my way of writing already. For me, it was way faster than the on-screen keyboard or any type of keypad. When I got the PalmOne Treo 600, I was dissapointed they took out the Graffiti software from the whole system and it had a tiny qwerty keyboard instead. That sucked for me. I had my Treo for several months now and just adapted to the qwerty keyboard system.
But I decided to get MobileWrite 3.5, mobile handwriting recognition software. Finally I can run Graffiti again on a Treo! I found this in a promotial PalmGear mailing list I am a member of and decided to get Sudoku and Kakuro since I got addicted to playing Sudoku already.
