You've never seen a router with a built in media server or storage or a print server? Many high end ones have this too. It's all converging. If it can be accessible via the Internet and if it's something people need an easy way to self host, then it will be included in an easy to use all in one device. Mark my words.

I do not want or need random apps on my bitcoin node. It only adds attack vectors. I like my hardware separate and dedicated. I will always prefer a separate modem, a firewall router, a wifi router, laptop, node. All this “everything in one box” is garbage.
