It was possible on the Acer model I got when it first came out, but it was still useless. A switch that wiped the whole thing back to defaults was needed to open a terminal and from there a shell script could install Ubuntu. It still ran the unmodifiable chromeos kernel with no updates and without some of the modules I'd like. And then the screen died.

It was junk. The EeePC was cheaper, lasted much longer and had Debian out of the box.
