I can understand why one would want to move from Kindle to another device, but this article starts by complaining that support is being dropped for devices from before 2013. I can even understand being upset by this, but I have absolutely no faith that whatever other device I switch to will still be supported in 10+ years. Could be. But I sure wouldn't count on it.
I don't have that faith either, but it still irks me when good hardware has to get chucked for software reasons. And this goes double for when those software reasons are about stupid-ass DRM.
But in this particular instance I don't consider it to be that bad for me personally, since I don't rely on being able to access Amazon DRM books. But a lot of perfectly working devices are going to get landfilled for this.
