Being cloud based is this "Code Anywhere", or "Code anywhere where you have Internet access"? The latter, in my case, would be "Code in less places than you could with your laptop and standard offline dev tools".
I travel a lot by train, which means a broken internet connection most of the time. Or when I stay in hotels or on a customer's site without wifi (3G doesn't always work well enough).
I gave a personal instance of the Cloud 9 (https://c9.io/) IDE a go a year or so back. Using git locally and enabling git on the server gave me collaborative and offline options.
I think some form of VCS access to these services determines their ultimate usability.
Can't speak for parent, but for me: on a train (lots of tunnels - no really, lots of tunnels[1]), on an airplane and in an airport (no free wifi) -- quite recently.
I have a complete copy of my production environment running locally in vagrant. I can code and run tests (3rd party APIs are all mocked) without any internet connection. I even have all the docs I could need cached offline in Dash.
The only thing I am missing is a local pypi to cache my commonly used 3rd party apps.
I use my laptop a lot on the go. Trains, Airlines, Pubs, Coffeeshops, and so on. Some places will have Wifi, or others I'll be able to tether. But I don't like to rely on having it to be productive.
