i like the idea of using a keyboard layout thats more efficient for typing common characters, less finger travel. But the thought of having to relearn muscle memory and not being able to just grab any old keyboard are both huge turnoffs for me. i assume for #2 i could programmatically remap keys with no effect in input latency? which then would require merely changing a few keycaps around... can anyone confirm if this would be the case?
