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".
Have XAMPP running or some local server. Go have a blast.
I think some form of VCS access to these services determines their ultimate usability.
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.
