Cons
Con You will void the warranty in most cases
Almost all of the official google chrome-books (See C720 series for an example) have a hardware write screw to protect the BIOS, To install SeaBIOS you will have to remove this screw, and in doing so you will void the warranty on your chrome book.
Con Removes Chrome operating system
If you go this route, you will lose access to the chrome os. It is not possible to dual-boot chrome os and GNU/Linux. Therefore if you would like to have the possibility of using chrome os in the future you will need to make a backup of the operating system.
Con Not intended to be a daily driver
This distro was written for pen testing and security work. It is not meant to be a day-to-day OS (unless that's your job).
Con Very old packages
E.G. Firefox's current version is 61 but Kali linux consists of its 52th version. Though kernel is not that old.
