I've not seen or heard of anyone else with one. Shipping volumes do not equal consumer purchases, so till I actually see people with them I'll take this as some sort of advertorial.
The good parts: Automatic syncing with Google services, such that you can wipe everything and restore, and it will automatically reinstall all of your applications and settings; encrypted storage and signed binaries so it is difficult if not impossible to load malware; and a very polished UI that gets you into a browser and gets out of the way to let you surf the web.
However, it does start breaking down when you want to start doing more CPU-intensive tasks like gaming, there is a big gap right now between where HTML5 gaming is and what native gaming (even through Flash) delivers. For a system that runs all apps through the browser, that is going to continue being difficult. Also, the almost-continuously-online requirement can be tough in some cases, but really I already have wifi everywhere I want to use it...
I can see it being a great option for 95% of day-to-day computer users, though. Mine was $250, and it definitely outperforms low-end laptops - great battery life, good speed, lightweight, etc.
Not to mention it can run a full version of armhf Ubuntu so I can still run tuxracer when necessary.
TFA may be an advertorial, but I see Chromebooks as the evolution of the original netbook idea - a cheap PC that goes everywhere and is good enough for most online activities.
Chrome Remote Desktop works through (most) firewalls, no configuration required.
In order to use Windows Remote Desktop, you'd need to open up your firewall by hand.
Also, Chrome Remote Desktop lets me use two-factor authentication to log in, where Windows Remote Desktop is much, much more vulnerable.
