Yup - it was the same for me with the 2016 SE. Still runs perfectly fine, we're still doing the same old CRUD web shit for apps, but apparently now our apps are so much more advanced that there's no possible way they could keep supporting that "legacy" hardware.

I'm totally with you, with that article. It is terrible how owners of slightly-old hardware are treated by software developers. Leaving potentially millions of users out in the cold because they just can't be bothered to keep a maintenance branch around and backport a few fixes to it. For apps that are by and large not complicated. So much waste sacrificed at the altar of developer comfort!
