I do see what you mean about the lack of choice, although I'd rather have all browsers implement one language consistently and and well, rather than a number of languages flakily and non-universally. The compiling-to-JS idea has a lot of potential I reckon. I've done a couple of GWT projects and the results work very well, much better than if I'd written the JS myself, and not noticeably slow. And debugging the app in Eclipse is so much nicer than using a JS debugger.
