The iPad Mini and Nexus 7 are competing in the smaller tablet space. People really like tablets of this size because they can be held with one hand, they can fit into a pocket (usually), and they’re great for reading and web browsing.
The iPad Mini is the more expensive of the two, starting at $329 for the 16GB WiFi model. At higher price points, more storage and LTE connectivity is available. It has an A5 dual-core chip with 512MB of RAM. The display is 7.9″ and 1024×768 resolution and 162ppi.
The Nexus 7 is just $199 for 16GB. You can double the storage for $249, then add HSPA+ data (coming soon) for another $50. It has a quad-core Tegra 3 CPU with 1GB of RAM. The display is 7.0″ and 1280×800 resolution with a 215ppi.
