The original iPad mini featured a 7.9-inch screen at 1024×768 (163 ppi). Internally, it had a dual core 1 GHz Apple A5 processor; 512 MB of RAM; and 16, 32, or 64 GB of storage. It had two cameras: a rear-mounted 5 megapixel iSight camera (1080p) and a front-mounted 1.2 megapixel FaceTime HD camera (720p). The original iPad mini used a Lightning port.
I found the iPad mini perfect for travel due to its small size, reduced weight, high-quality display, and 10-hour battery.
