I own a Acer c720p Chromebook and I have to say it is a wonderful machine. I now only use my main PC for programming, and I even do that sometimes by SSH from my chromebook.
Main point:
* Great battery life
* Lightning fast
* Small/Thin
For me it is a perfect cheap laptop to use as a goto for all my less resource intensive activities. (reading, youtube, chat etc.) I might get a bigger 15 inch one so I am happy to see Chromebooks developing. I am having a hard time figuring out who would use a chromebit though..
I use an Acer C720P as well, for everything including programming, via Cloud9 (https://c9.io/). Cloud9 has been almost exclusively the platform for all my development since 2013. Having my entire workspace state synchronized across machines, saved whenever I'm not using it to be resumed precisely as it was, sandboxed from causing or falling victim to issues with my desktop, is invaluable.
I switch off between my desktop and my Chromebook whenever I go out, or even just when I want to lie down instead of hunching over at my desk. I experience no disruptions from doing so.
The only real complaint that I have is that ChromeOS's use of alt+arrows to emulate Page Up/Down keys interferes with a few important default C9 key combinations (alt+shift+down to copy a line getting converted to shift+pagedn).
I'm using C720 with chrubuntu, a full featured ubuntu along with the native ChromeOS for dual booting. Some guys may prefer crouton and it's similar.
I should say I use my C720 everyday on my train to work mostly with linux. It's with x86 CPU, just as a normal laptop. Its performance, battery and portability are great for me as well. I really love travelling with it.
