This may not help with PPCs, but I use TealScript on my Palm. I tried Fitaly for about 3 months and could not remember the key placement. I spent too much time trying to figure out where the next letter was in that arrangement. Since I write in all caps, I'm fairly quick with graffiti. Graffiti2 sucks badly-who came up with the idea of 3 strokes to create a single punctuation mark?
I used the latest script profile on the Teal Point site, then went through the retraining, where you enter 500+ alpha characters and 200+ numeric. I ran the autotuning, which was fascinating to watch and took over 2 hours. Finally stopped it when it had 26 matches left to correct. I had to tweak the "d" recognition a bit, but it will now recognize my handwriting without me slowing down a bit. It's a great program.
If I have to do something quickly, I have a small Clairefontaine notepad for those entries. I put one item on the paper and then it gets tossed to my inbox for processing.
