I haven't used this new Amazon Cloud9 offering, but from the initial impression from the blog post, they've traded in the easy of use that Cloud9 once had for a deeper integration into the AWS ecosystem. The screenshots I saw were not something I'd want a greenhorn to have to walkthrough.
I'm not sure what future I expected when Amazon purchased Cloud9, but I mourn the potential loss of an awesome cloud based IDE that beginners could easily pickup (my mind can be swayed once I give it a try though).
I even think this benefits high schoolers and college students. If AWS gives credits to schools who implement Cloud9 in their curriculums, they're going to get a big win here.
I think this feature is called "Workspaces" in Chrome.
