This person is confused about the security intentions of the device. Google tells you how to install alternate os' on there. It doesn't have easily upgradable storage in part because that makes them cheaper, but some have had upgradable stoage. My chromeos Asus desktop brick like device has upgraded memory and storage. Look at Mac laptops for serious anti upgrade efforts. Part if the restrictions are to prevent virii or other rootkit like takeover of the machine.
