Great points. I just want to toss out an example of why you might want an OS to use with flash of decent size to do wear leveling on everything. The classic example I give is a media player subject to power interruption and you don't want to include an internal battery in the design for graceful powerdowns, so the player needs to save a checkpoint of play state every ~5 seconds so the device can resume intuitively. Such as indexing back to your position in a 40 hour audiobook. You're also going to have menu navigation and a combination of changing settings and device local media library changes. And now comes along some Internet angle so there are C libraries that implement browser functions and that means cache and cookie writing. And software updates. Ring buffers are smart but there's a whole lot of writing going on here! It would be great to code everything in high levels so if it emulates properly on a desktop, once it's pushed into the devices (say a generous 128GB flash with 28GB reserved for the system) the devices will have a 20 year lifespan with no batteries to fail or leak.
