I sometimes use stenographic handwriting, which is different from the question. One insight I had is that swiping on the iPad is fundamentally faster than stenography, because the information density of these curves is higher: you have more context sensitive starting point and swirls. The only thing that is even faster is speech recognition (google > siri) ... and maybe the stenography OP asked about, which is probably not worth the learning curve given how ubiquitous speech recognition is becoming.

I've been thinking about touch screen stenography too. I think it could be much better for you physically.
