"If someone doesn't have JavaScript, he's either extremely paranoid (and belongs to a really minor minority) or using hopelessly outdated browser (a minority that most likely wouldn't be a good customer anyway)." With the trend towards mobile devices (as in not chained to a desk) this introduces far more complexity to whether client-side rendering is viable than whether "javascript is turned on in the browser". (Here's some notes I made about that a few months ago: http://isolani.co.uk/blog/javascript/DisablingJavaScriptAskingTheWrongQuestion#javascript-obstacles http://isolani.co.uk/blog/javascript/DisablingJavaScriptAski... ) The mobile trend also blows a big hole in the article itself: The CPU power of mobile devices is quite well behind that of a laptop or desktop. Probably about 2 or three generations behind. So the perceived performance will still lags behind.
