Following the debut of the 27” iMac with Retina Display last fall, Apple has now brought the higher-resolution screen to its smaller sibling, introducing the 21.5‑inch iMac with Retina 4K display ($1,499). Pushing the display up to a 4096 x 2304 resolution, with 9.4 million pixels, the new model also sports a 3.1GHz quad-core Intel Core i5 processor and 1TB hard drive with Intel Iris Pro Graphics, two Thunderbolt 2 ports, and 802.11ac Wi-Fi with support for wireless speeds of up to 1.3Gbps.
