What do you think of my
WoW minipets site? It doesn't have a whole separate 'mobile version', rather just some mobile-specific (via media queries) CSS that make it work better on a small screen. I don't think there's even any mobile-specific JS, and it uses the full version of jQuery.
It depends on the site but do wonder why some even have an entirely separate mobile version – if they didn't weigh their pages down with so much crap it wouldn't be necessary in may cases.
edit: I've only tried it on my iphone so there might be some issues in the various Android browsers, although since they're WebKit-based, hopefully not.
