I have found that the keyboard works better for some apps particulary the
spreadsheet, but Graffiti is easier for most others. A few things that I
do to write faster is to not use caps or punciation. Most of the time
you don't need them (taking notes on the jotter or making appointments).
I write in bullet points and it is easy to return to a new line. I've
timed myself at up to 18 wpm (30 - no way!) using this method. Also, I
have found it easier to use the Graffiti box if you're often switching
between numbers and text. The Graffit box also helps for entering
appointments or phone info where the writing space is small.
