The Samsung GALAXY Tab 2 7.0 offers a 7 inch Super LCD screen with resolution of 1024 x 600. That works out to a pixel density of 170ppi. A dual-core 1GHz processor is under the hood with 1GB of RAM. The tablet is available with 8GB or 16GB of native storage and a 32GB capacity microSD slot is available. A 4000mAh battery powers the device. On back is a 3MP camera with a VGA front-facing shooter. The latest update brought Android 4.0.3 to the device.
Samsung Galaxy Tab 2 10.1 is equipped with a 10.1 inch Super LCD screen with a resolution of 1280 x 800. The pixel density is a rather poor 149ppi. Under the hood is the well known Qualcomm Snapdragon S4 Plus MSM8960 which is a dual core 1.5GHz processor for this tablet. The Adreno 225 GPU handles the graphics and 1GB of RAM is on board. 8GB of native storage can be expanded using the 32GB capacity microSD slot. The 7000mAh cell keeps the power on. A 3MP camera is on back with a .3MP front-facing camera available for self-portraits and video chats. Android 4.0 is running the show.
Lastly, the Samsung GALAXY Note 10.1 has the same screen size and resolution as the Samsung Galaxy Tab 2 10.1, but under the hood is a quad-core 1.4GHz processor and there is 2GB of RAM on the tablet, making multitaskers happy. 16GB, 32GB or 64GB of native storage can be pumped up by an additional 32GB using the microSD slot, and a 5MP camera on back has LED flash and records video in 720p. A 7000mAh cell keeps the hamsters' wheel spinning and Android 4.1 is now installed.
It's just like that song by Chris de Burgh, "Tablet in red".
