Interestingly, I also studied piano for many years (from age of 5 until 18 I guess). I agree, wrist flexion is important, and I definitely do flex my wrists (sometimes in a seemingly exaggerated manner) when playing piano, however, for typing, I can comfortably type anything I want, including special characters, without flexing my wrists. Not sure if this is a sign of a well designed layout or RSI waiting to happen

Perhaps weighted keys make the difference?..
Yes, that's a very good point. The keys I'm using are Cherry MX Clears which have an actuation force of 55cN. From my own experience, it would require a lot more force to depress a piano key. So yeah, maybe wrist flexion is pretty much required when playing piano to avoid muscular fatigue in the fingers.
>it would require a lot more force to depress a piano key
55cN is a little on the high side for force needed to depress a piano key ("touchweight"). But the piano is velocity sensitive, and pressing with the minimum force won't get you any sound. Playing loud notes takes substantially more force.
