Playdate's screen isn't e-ink, it's a 1-bit LCD

You probably wouldn't want the refresh rate of e-ink for a gaming device.

You're right. I literally have one sitting on my bookshelf I just haven't touched it like, since about a week after it came out.

Wouldn't be impossible. I'm old enough to remember the original B+W game boy, and my B+W e-reader refreshes faster.
