I absolutely 100% hate, hate, hate mobile-optimized design sites, particularly ones that disable zooming. Up until now, I've done pretty well spoofing a desktop user agent to get the full pages, but with the advent of responsive design, it seems like more and more sites are feeling comfortable using viewport meta-tags to set user-scalable to false, which means that I am in effect forced into using the horrible mobile sites.
From what I understand, viewport tags are ignored by desktop browsers - is there a browser on Android which does the same thing, preventing web sites from removing key functionality from my phone? Maybe a Dolphin add-on?
I think potentially a greasemonkey script excising the offending viewport tags would also work, but I'm not sure there's a stable version of greasemonkey for android yet, and it might be preferable if the browser itself were built to always allow zooming.
