I think the question is one of what should be mainstream. I think most people will value portability over all else once it can come close to matching local apps. Because while it might not take you or me much effort to move our data from computer to computer your average user dreads that. Your average user lives in fear of their computer crashing because they'll lose access to their data and have to pay someone $300+ to get it fixed. Or that they'll get a virus and lose access to everything. Or whatever else.

For them the right tools is one that gives them the ability to walk over to another system, put in their info and be back up and running.

For people like you I think there will always be Linux versions out there and who knows what else. The cloud isn't right for everyone. Those of us who support ChromeOS just realize most people aren't like you.
