For the 85 year old grandpa, absolutely. I have an uncle (around 85) who went through multiple computers (edit: all Windows), and kept getting virus and other malware; he kept falling for sites that would advertise to "clean" his computer, and it just kept getting worse and worse as a result. The instant he switched to a ChromeOS-device, that all went away, and my tech-support burden also went away instantly. His biggest issues with ChromeOS is printing (his printer of the time was not compatible with Google's cloud printing service), but after he bought a new printer that basically went away too.
