When I'm developing early proof of concepts apps, I like to use DropBox to store my code so I can get access to everything at work and at home. Plus if you store your project in the Public folder, you can generate a publicly accessible url for your .html pages which will correctly render in the brower (i.e. correctly run your HTML, CSS & JS), essentially turning DropBox into a sort of limited hosting provider.
If you decide to use Sublime, you can download the portable version (no install required) & save that to DropBox too; this way you have access to all your code AND a full AngularJS IDE from wherever you use DropBox. Which basically means you have a full dev environment in the cloud. Pretty sweet!
