My primary keyboard now is a Kinesis Freestyle Pro, and my favorite feature isn't the split, it that it's programmable and has a split spacebar. The main reason I moved my hands around before was to use the arrow keys, and now they are mapped to [right spacebar] + [IJKL]. I have also expanded a little to use U and O as backspace and delete on that same layer. I don't think I could ever memorize 3+ layers, but this small use of a second layer that is very easy to access has been great for me.
