You can get a similar e-ink experience with the Dasung E-ink Phone Monitor. The advantage is that it just mirrors your phone display and acts as a touch screen. You can keep using your existing apps without having to transfer data to a new device, and when you upgrade your phone you're also upgrading your e-reader. Just make sure to get the wired or wireless option suitable for your phone type.
