Hey ricardino - as I say, I got the impression from various tutorials about it (and blue something - the other similar grid-based thing (ooh - I just had a Tobias Funke moment)) that it helped if you were particularly well versed with things CSS already.
Sometimes I read those kinds of comments as 'you should only use this if you don't need it'. Mind, a number of CI people suggest new users learn PHP first, before picking up any PHP framework. Probably similar logic.
But no, never used it in a real site. I suspect it'll give you a more professional looking site simply because so many sites use a fixed width approach (ie. you'll be part of the popular crowd
I hover between a netbook (1200x) and a desktop (1680x) and a 960-limit is annoying on the former because I have so little space and really hate to waste it, and on the desktop it just looks wrong. Yes, I don't always use full-width windows while I browse, but then it means I have to match my window width to the web site's width, and that seems to be missing the point of HTML, IMO.
Having said that, I can see that for some types of sites it would probably work really well.
