Bootloader locked?
Is the bootloader locked or are there any methods in place to prevent you from changing the OS?
It would be interesting to have one of the "book tablets" that was as free to use as a desktop computer where you could put any OS on it.
In particular I'd go with Fedora on it, just for kicks :-D.
I really dislike the way modern devices are becoming more and more locked down though, so I'm hoping one day all that just stops and they give you a device and say "Here you go, do what you want with it".
