Looks like the iPad has some competition. Google unveiled its first tablet computer, Nexus 7, at its annual developer conference on Wednesday. The 7-inch device, built and co-branded in partnership with hardware maker Asus, will be priced at $199. It features the new 4.1 Jelly Bean version of Google Android, has front-facing camera, a 1280x800 resolution screen and an Nvidia Tegra 3 processor.
