Bought a Chromebook for an elderly or tech illiterate parent-relative

Sorry if this the inappropriate forum to ask this question. My father is in his middle 50s and wants to get a computer for simple browsing and emails, maybe some skype. Windows 8 is kind of a cluster and I sure as hell can’t afford a mac-book. I naturally though Chromebook because he does quite well with his GS5 and I though the interface seemed similar. Folks in a similar situation how have your experiences been? Any tips or tricks? I’ll be in charge of running tech support and teaching him how to use it. Anything I should look out for?
