Sure, many of the people buying this won't be running ChromeOS.. but then they shouldn't really be complaining that it doesn't fit their needs. A Chromebook is not a general purpose device, it was specifically designed for a narrow use case, ChromeOS. The fact that you can do something else with it, does not mean it was designed for that.

I'm not going to buy a vehicle designed for hauling freight, and complain that it isn't sporty enough. Which, in my opinion, is what complaining about the lack of storage in a "Webbook" is like. You're buying a device, specifically tailored and designed for people who are using a web based operating system. It doesn't even let you install things by default, outside of web apps.
