This week, at its I/O conference in San Francisco, Google announced its first branded Android tablet.

But wait – that's not strictly true. It was actually Gizmodo that announced the Nexus 7, providing wholly accurate details of its pricing, specs, release date, and branding three days before Google lifted the lid on its project.

It was an astonishingly comprehensive leak, and one that highlights just how difficult it is for even the world's most secretive companies to keep their projects under wraps. The day an Apple engineer left his prototype iPhone 4 in a bar will stand forever as testament to this fact.

It also highlights just how good a job Microsoft did of keeping its Surface announcement under wraps. Hours before the scheduled press conference, blogs were insisting that Microsoft was gearing up to announce a Barnes & Noble slate with Xbox Live compatibility.

How wrong they were. But now's not the time for gloating – instead, let's move on to our bite-sized overview of the last seven days' worth of news.
