I'm curious which standards that are being used are only outcome of need of backward compatibility that, if we had to select once again would be selected differently. Any ideas? 1) Keyboard? Dvorak vs. Qwerty? Or is it a myth? (Or should there be a separate keyboard layout for every language?) 2) Is the voltage properly set (in my country AC 230V 50Hz)? I know that with lower voltage there is higher loss, while with higher voltage electrocution is more dangerous. Which would be optimal under contemporary technology? 3) Any other ideas?
