As easy as transposing music (Score 2, Interesting)

I find switching between QWERTY and DVORAK as easy as transposing key signatures in music. Ask any studied musician about transposing from C major to G major, it is just a tiny mental shift, that's all. I must admit, though, that going from a regular DVORAK to a Microsoft "split" keyboard , natural keyboard, or ergonomic keyboard is very frustrating.
