The original iPad Air models have the same 9.7" Retina display as the earlier iPad 3rd Gen and iPad 4th Gen lines, but are "20 percent thinner and 28% lighter" and have a much narrower "bezel" around the display, which makes the iPad Air "feel" quite a bit smaller than its predecessors.

All iPad Air devices -- including this Wi-Fi capable model (A1474) -- are packed in thin "Space Gray" cases and feature a 9.7" 2048x1536 (264 ppi) LED-backlit IPS touch-sensitive display, a dual core 1.4 GHz Apple A7 processor, 1 GB of RAM, and 16 GB of flash memory storage

Other notable features include dual cameras -- a rear-mounted 5 megapixel "iSight" camera capable of shooting stills and 1080p video and a front-mounted 1.2 megapixel "FaceTime HD" camera capable of shooting stills and 720p video -- dual-band 802.11a/b/g/n Wi-Fi with MIMO capability, and Bluetooth 4.0, as well as dual microphones and speakers. Connectivity to computers, if desired, and power is provided by the Lightning port.

The battery life of this iPad Air model is reportedly 10 hours "surfing the web on Wi-Fi, watching video, or listening to music.",  of-course these times differ with a refurbished ipad. Batteries hold charge , are not warrantied.
