Memory	The Google Nexus 7 has 16 GB internal storage of which only 13-14 GB will be available to users.	The iPad mini starts at Rs 21,900 for a 16 GB WiFi only version.	The Samsung tablet comes with 16 GB internal storage along with a micro SD card slot for storage expandable up to 32 GB.	The Samsung has natural advantage as it offers 16 GB internal storage along with micro SD card slots for expanding memory space. While iPad mini scores over the Nexus for providing cellular connectivity and enhanced internal storage on certain versions, it loses the plot with increasing price vis-a-vis Samsung.
Camera	The Nexus 7 has a 1.2-megapixel front camera. No rear camera.	The iPad mini comes with a 5 megapixel rear camera and a 1.2 megapixel front FaceTime Camera.	The P3100 comes with a 3 megapixel camera in the rear and a VGA (0.3 megapixel) camera in the front.	If a camera is a must have in your 7-inch tablet, then the Nexus 7 turns out to be a big disappointment. On the other hand, iPad mini scores with high-quality camera on both front and rear, which is a big plus in a 7-inch tablet.
Operating System	The Google Nexus 7 comes with the latest Android 4.2 Jelly Bean version.	The iPad mini ships with Apple’s iOS 6.	Samsung has just started pushing Android 4.1 Jelly Bean update	If you are a Google/Android junkie, the Nexus 7 tablet will end up being your choice. Unlike other altered versions of the OS this one is pure Google.
Battery	The Nexus 7 has a 4325 mAh battery which is expected to offer 8-9 hours of power on active usage.	The iPad mini offers up to 10 hours battery life on just Wi-Fi and up to 9 hours on cellular data.	The Samsung Galaxy Tab 2 (P3100)’s 4000 mAh battery can last more than a day with normal usage.	No clear winner, but it is yet to be ascertained whether Nexus 7 can live up to its claim during active game usage.
