>The X200 was way easier.
I think to most people, the idea that one can have coreboot by just messing with the software seems appealing. From what I understand, one always need an external flasher for the Thinkpad while you don't with Chromebooks. So that's a huge factor in accessibility in favor of Chromebooks.
>I also tried to compile my own C720 coreboot and flash that, but ran into problems.
I actually didn't compile my own version of Coreboot. I guess at some point I'd have to trust someone. But it feels very funny to me that I trust a random guy on the internet nicknamed MrChromebox to do the right thing instead of Intel. But then, even when I compile my own firmware, I have to trust thousands of other people who work on Coreboot to not have performed any underhanded tricks, my compiler to be free of defects, etc. "Reflections on trusting trust" hits home hard. I think all in all it does sound like that "having software/hardware we can control when we want to" (aka Stallmanism) is a more realistic goal than "better security."
For the ezpi4me project though, I tried to make the scripts as simple and easy to understand as possible, so you do see all it does. This is one project that I completed recently that I'm quite fond of, especially given I haven't been very productive and inspired to do things for a while :)
