Look, if you really need to get a coin cell onto the internet, then go for it. But I don't think your comments on this thread represent good advice for most engineers building typical devices. Insinuating that anyone who doesn't agree with your view is technically challenged is also kind of pathetic.

Expectations around what an internet connected device should look like and be capable of changed permanently with the launch of the iPhone in 2007. There will always be special cases like yours, but they are increasingly (sadly?) relegated to smaller corners of the internet.

I did it your way for years. Every company I've ever worked for that started off with a microcontroller based networking solution eventually migrated to an application processor because users and non-technical management kept demanding iPhone-like behavior that was either too difficult or too time consuming to deliver any other way. People expect a lot more functionality than just TCP sockets and web interfaces nowadays.
