I'd guess that it's actually quite an issue for JS heavy pages. This would probably benefit anyone doing signification in-browser apps in JS.

  Hmmm, checking for example Gmail which is arguably a heavy page it's got 4meg of requests for various js + html files. So 16meg if expanded to 32bits per code point. But it's using 160meg of ram. Strings are not where all the space is going it would seem.

    The raw source code is not the only strings in an application. Gmail especially will be heavily manipulating the DOM and a variety of other things (JS properties, JSON requests) which use Strings internally.

    If you actually read the linked article, it has measurements for how much RAM strings use in Gmail. For the particular case of the article's author, it was about 11MB of strings before the changes he made; it was about 6-7MB of strings afterward. Your mileage will vary depending on what actual mails you have, of course. Note also that comparing this to the Chrome numbers for overall Gmail memory usage is comparing apples and oranges: Firefox tends to use less memory than Chrome. You'd want to look at about:memory in Firefox to see how much memory that gmail page is likely using.
