I mean as long as the system is taking inputs it really doesn't matter when the screen shows them to you. Modern systems can still do what old systems used to do and you're apparently not doing stuff in a terminal right? In DOS you could start typing all of your commands while the operating system is starting and everything would be buffered including the enter presses. Long and short of it I'm just saying don't worry about the screen responsiveness of eink and just enjoy writing.
