Google had a lot to announce at its I/O keynote yesterday, but if it's all been too much to take in then this could be a solution of sorts — a guidebook to the new Nexus 7 tablet on Google Play. The 84-page tome isn't just restricted to those interested in the Asus slate, however, as it acts as an introductory guide to the Android platform and Jelly Bean in particular.

Now, admittedly you'll probably want an Android device to download and read the book in the first place, but even experienced users might find it useful to delve into the new Jelly Bean features. For others considering the Nexus 7 as their first Android device, it might make for an appropriate way to test the device's capabilities as a reader. It's available now in countries where books are sold on Google Play.
