Apple iMac with 4K Retina display review: Apple packs more pixels into its smallest iMac

 

Last year's addition to the 21.5-inch Apple iMac line caught our attention by cutting the starting price to $1,099 (£899 or AU$1,349) and positioning itself as essentially a MacBook Air recast as a desktop system; the new version for 2015 aims higher.

Apple upgrades the 21.5-inch iMac with a stunning 4K-resolution display, along with faster processors and Thunderbolt 2. The redesigned keyboard, mouse and trackpad all have rechargeable batteries and lightning connectors

The new processors are still one generation behind Intel's latest and there are no discrete graphics options. No HDMI input means it can't double as a TV monitor

The smallest Apple iMac trades up to a 4K display, and jumps to newer, but still not the latest, processors. While the design hasn't changed, newly crafted accessories with rechargeable batteries and Lightning connectors add flair and convenience.
