My Xteink X4 arrived a few days ago! Ordered one after the write-up on Aftermath; already really enjoying the convenience and form factor. I’ve successfully reduced some of my phone time each day by grabbing the X4 instead.
After some deliberation, I opted to flash CrossPoint Reader over the base firmware. As is the nature of things, there are already at least 2 CrossPoint forks out there already, each of which is doing some different things: Papyrix Reader and CrossPet, “Your pocket e-reader — with a virtual chicken.” I’ll be keeping an eye on all three projects.
And there’s also ReadMe.club, “Your Xteink Community Hub,” which has a good selection of resources including formatted and optimized wallpapers.
