Apple announced on Tuesday the iPad mini the highly anticipated pint-sized version of its popular tablet. The device has a 7.9-inch display with a 1024 x 768 resolution, Apple A5 processor, and a 5-megapixel rear-facing camera. With a starting price of $329 for the 16GB Wi-Fi model, the tablet is the least expensive iPad ever made. The iPad mini isn’t the first small tablet to hit the market, and will face some tough (and cheaper) competition.
