On my Galaxy Nexus I have an option "Load the Desktop version of this site". I don't see this option in the new Chrome Beta though. On iOS I had to jailbreak and install an SBSettings toggle to change Safari's UA, which restarted it, but then it worked more reliably than the one in my Android. But yeah, not having to root or jailbreak and getting the functionality I need is one of the long list of reasons I will never look back to Apple's ecosystem. The future is open, the future is web apps, and there is no place for closed ecosystems no matter how rich or extensive they may look now. Give people open tools and we can have more web apps than app store has apps in a very rapid time.
