You cant edit? I was able to open a docx through drive and it asked to convert the file to edit. Once I converted, it allowed me to make any edits I needed. All fonts/content were correct. I havent tried it with an excel sheet yet, so I dont know how it will convert that. As far as the OS goes, you basically do everything through the browser. Instead of local programs, it runs off the cloud (hence google docs/music). Granted, some programs now have an offline feature (docs/gmail) but dont expect it to function much when you arent connected. They have very small hard drives so you wont have anything stored locally. If you dont have reliable internet, forget about a chromebook.
