As an aside,
Most products in the palmtop category are designed to be information providers rather than high volume data recorders. Years ago there was a device that was portable that had six buttons spaced for the fingers (two under the thumb one being a toggled caps lock). It was modelled on the court recorder devices used in trials. Although there is a learning curve in getting proficient and fast with the input, it was possible to use it (in skilled hands) to record dictation in real time, alas the idea never caught on and designers turned to using stylus type devices instead.
