We went into Google I/O hoping for hardware and gadgetry; instead, we got three and a half hours of software and services - gaming, messaging, Larry Page wistfully envisaging a geeky utopia. You can perhaps excuse us for getting carried away in our expectations. I/O 2012 was a huge spectacle, with lashings of shiny new hardware only overshadowed by skydiving Glass daredevils and Sergey Brin looking moody on a rooftop. In contrast, 2013's event brought things a whole lot closer back to the developer-centric gathering that the show had originally been established as. Glass was conspicuous by its on-stage absence, and the new Nexus tablets that had been rumored were also no-shows; the emphasis was firmly on how the components of Google's software portfolio were being refined as the mobile and desktop battles waged on.
