On Wednesday morning, the first day of I/O 2012, Google made what was perhaps the single most noteworthy announcement from the show: It showed off the brand new Nexus 7 tablet, which will be released in the middle of July with a starting price of $199. The tablet runs the latest version of the Android mobile OS, v4.1, or "Jelly Bean." (The fact that only a handful of ," is another issue altogether.)

The Nexus 7 is 7-inches in size, it weighs 340 grams, and the tablet is built by electronics maker ASUS. The tablet has a 1280x800 HD display. It has a variety of wireless connectivity options including Wi-Fi, Bluetooth and NFC--no cellular version has been announced yet. The Nexus 7 packs a Tegra chipset with quad-core CPU and a 12-core GPU. And it has a front-facing camera, though it doesn't have a camera on its rear panel. The Nexus 7 tablet should be released in mid-July, but you can preorder it from the Google Play store today for $199.99. Check out my and read more about the .

Google also detailed some of the enhancements for Android 4.1 Jelly Bean, which should be rolled out for Galaxy Nexus, some Galaxy S devices and Motorola Xooms in July--sorry HTC users, no Jelly Bean for you just yet.
