I might be the snowflake here. Every time I tried to learn 10 finger I got bored and broke off. But I developed a reasonably high speed anyway. A few years ago I started using Neo which is just awesome, but optimized for German. (Still it has some features Colemak and Dvorak are missing, maybe someone likes to dig into this and prepare an engl. version.)

After that I basically had to relearn typing, and did so the same way. My current type speed maxes somewhere at 400CPM which is way more than I actually need.

The OP has a great point. Learn your tools! In case of the computer that includes to use keyboard shortcuts and optimize commonly done activities.
