As the Google I/O (GOOG) developer's conference gets underway (live blog), images are leaked of Google's much-rumored Nexus tablet. It looks, well, like many other Android tablets on the market. Also, the company's rumored home media streamer has appeared on Google Play. It's called the Nexus Q, runs on Android, has a built-in amp, looks like an oversized 8-ball, and will sell for $299 (3x as much as Apple TV). You can also buy accompanying Triad speakers for a mere $399.
