Re: quite confused here
You are indeed confused. The running OS is read-only and signed and checked on each boot and as each process is loaded it's also signature checked, it's physically impossible to boot something that's not the Google image, nor is there any way to change it at runtime. There is a cache partition for all browser data, that's it.
It's no coincidence that Chromebooks are generally not part of hackathons, or if they are, they walk away unscathed. The downside of course is they are limited in what they can do, but the vast majority of people would fit perfectly with what they can do. The people I have carefully sent towards a Chromebook, can't believe how cheap and hassle free they are, and I never ever get support calls, they just work, end of.
