Cons
Con Not for daily use
Tails is a privacy focused Linux distro. The updates that you will receive are only for improving privacy and not for improving user experience.
Con You can't install it to a hard drive
Con Saved states are not present for security
For security reasons, saved states are not supported in Tails. Files can be stored in a separate, persistent volume which must be accessed with a root password. Personal settings (e.g. -- keyboard layout, window settings, etc.) are not saved persistently across reboots. This can be a hindrance for anyone not using English as their language, or not using a QWERTY keyboard layout.
Con Only GNOME desktop environment
Con Slow internet
Tails uses the TOR network and as a result the internet on your computer will be very slow.
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.
