There is a very interesting piece over at Find Law blog, it compares the Nexus 7 Android Tablet against the iPad 2. Apparently size matters. The 7-inch Nexus is easier to carry around and its rubberized back is comfortablet. However, the iPad 2 9.7 inch screen is much better for work.
The review is in favor of Nexus 7, especially due to its price and 7-inch screen. For more details, please check out the Find Law blog post.
