Is the editor/IDE really the limitation? If anything web-technology-based IDEs are usually the ones wasting resources nowadays, my long-lived emacs session running the SLIME environment to interact with common lisp uses a meager (by modern standards) 110MB of RAM. I used a very similar setup 15 years ago on a computer with 512MB of RAM and a single-core 1.5GHz CPU.

You can already develop very comfortably on a chromebook if you're willing to forsake the bloat of the web. Actually if I can trust Wikipedia a modern Chromebook outperforms my main desktop machine a decade ago. Putting everything in the cloud doesn't strike me as a great step forward, although it could have its uses.

Well, you might be biased by the fact that you are fluent in emacs and/or vim. 90+% of modern programmers use heavier IDE's in their work.
