I have both a Nexus 7 16GB Wifi and an iPad mini 32GB Wifi.

Honestly, they are both good in different areas.

The higher price for the iPad mini can be justified by the availability of certain paid apps. I also prefer to ready books and browse the web on the iPad mini because of the bigger screen. I like iCloud auto-sync, A LOT. 3D is better on iPad mini (shockingly... I thought Tegra 3 was the bomb).

For everything else, such as Papago M9, I rely on Nexus 7.

Choose wisely folks!
