You can find a comparison on the CrowdSupply page. Xteink X4 does not let you easily replace the battery, for example.

    Thanks for mentioning the comparison. It was farther down than I had previously scrolled. TL;DR frontlight, touchscreen, user-replaceable battery, but also bigger bezels, double the price, and looks to be 3D printed instead of injection-molded. Comes with open firmware instead of just allowing it, but that's a non-factor to anyone with a little computer knowledge, which I suspect includes basically every potential buyer of this sort of device.

    The XTEink X4 Pro has a front light and a touchscreen, but needs a magnetic adapter to charge (comes with one and they're cheap to replace, but still an extra thing to lose). It's $110 MSRP.
