Different people have different needs. I could use a computer without an internet connection (reading, writing, programming, games, photo/image editing), though I must admit that it would be less pleasurable than it was 20 years ago.

Businesses are a different issues though. They have to "create" stuff with computers. It may be as common as bookkeeping or as sophisticated as engineering. It may be possible to complete online, or it may only be doable with software running on the user's workstation. Chromebooks are not the perfect solution here, albeit they may be better than Windows in some cases.
