The split allows you to open up your shoulders and straight end your wrists. Tenting or tilting does make it even more comfortable because it gets closer to a more vertical (handshake) position. I agree with you that movement, rest, and stretching is key. Staying too long in the same position is not good.

Exactly my point. The Segway(tm) is also a great way to avoid sitting all day, but perhaps taking a walk is even better.
