Today I value web stuff for one thing and one thing only: they run in the best sandbox we have. I can run untrusted programs from hackernews folks without worrying! I wouldn't do that with native code of course, way too easy to hack me. But they won't waste a browser 0-day on random HN readers... Whatever can be done in the web, I usually like to do it there as no-body has to trust my code then.
