I genuinely liked the Palm Graffiti. It took a couple of days of playing Giraffe to get used to it, but afterwards the speed and precision was quite decent. Of course it's nothing compared to modern swipe keyboards but still.
Agreed, I often miss Palm's Graffiti input, I don't remember it well at all at this point I think I tried a similar input on android and went back to gesture keyboard. Of course, I kind of miss even developing for Palm as well, which was far simpler an experience than what Android and iOS are today.
