Google's second keynote didn't contain as many hardware announcements as the first, but the company did provide a closer look at its ancillary software. The first major announcement was that Chrome would be coming to the iPhone and iPad, and we've already gotten a chance to give it a spin. Next, it was announced that Google Drive would be coming to iOS and Chrome OS, featuring optical character and image recognition, as well as real-time collaboration. Google also unveiled a totally new product — Compute Engine — which is a direct competitor with Amazon's EC2 (Elastic Cloud Compute) service. There's plenty more information where that came from, so if you didn't get a chance to watch it yesterday, all 79 minutes of Google's second I/O keynote are ready to be watched below.
