Just wanted to thank you for this comment. I have very broad shoulders but have been hacking on Apple keyboards for a few years now - the results are that I have essentially permanent internal rotation of my shoulders. This has led to not being able to breathe properly with my diaphragm, which causes all kinds of issues!

I missed the pre-order, but I grabbed a Logitech ergo kb from the local Microcenter a few days ago and already the changes have been substantial! Of course I am also focusing consciously on the breath, using my diaphragm not my stomach or clavicles. Thanks again! I never considered it until I read your comment.
