I had one of these, it wasn't very hard to learn - the movements were very similar to querty. I started getting RSI and this helped a lot. Now I learnt a bit about typing skills and ergonomics I am fine on a regular keyboard, but I would have kept on with the datahands if not for its massive lack of practicality. Basic typing was great, but using it on a mac for programming was not so great - all the modifier keys were wrong, and the PS2-USB connection was flaky. Not to mention carrying it around with a laptop was basically impossible without a dedicated case...
