Probably user-agent plus better translation of touches into mouse events. To some extent, though, I'm having a hard time understanding how this is useful. Most sites are responsive these days, and it's been a long time since I remember getting a separate mobile site on an iPad. They showed Google Docs as an example, but even if you could use the desktop version of Docs on an ipad, it seems like it would be really uncomfortable to do so (and I though that was the whole reason for not making a touchscreen mac in the first place)?
