The entire conceit of Chrome OS is that it's sort of a diet computer. It does the basics, and just the basics. Chrome OS will give you internet, basic word processing through Google Docs, video via YouTube, and the rest of Google's web services including a free as in freedom lifetime direct hotlink to the NSA. You can stick in Chrome extensions for added "apps" if you'd like, possibly even a future NSA all inclusive backup app. But you're not going to get any full software here, because Chrome OS isn't compatible with anything outside of itself. And that's been OK, because Chrome OS laptops have been very cheap: a few hundred bucks for the essentials is a good deal. Thirteen hundred dollars for those same essentials is a very, very, hugely, wow-bad deal.
I have an ASUS C200, and because lately I have a need for a word processor and browser on the go, I love it despite its limitations. It's cheap and light and has insanely good battery life with an operating system that stays out of the way. I emphatically don't feel a desire to go out and buy a >$1000 chromebook, though (if I bought the pixel I would probably go and replace the OS with linux, whereas on my C200 I haven't even bothered to install a linux chroot).
