Apple iMac review (21.5-inch, 2015): 4K is optional, faster hard drives shouldn't be

 

The iMac is still the all-in-one to beat, with an optional 4K display on the 21.5-inch versionand improved color accuracy. Creative pros will gravitate toward the 5K27-inch model, which offers better specs, while casual users will appreciate that the...

4K resolution is now an option ; Improved color accuracy ; Attractive design ; Input devices are now rechargeable ; Robust audio

Faster Fusion Drives are an up-sell, even on more expensive models ; Slow start-up with the entry-level 5,400 rpm hard drive ; Discrete graphics no longeroffered on the 21.5-inch iMac

The iMac is still the best all-in-one, with an attractive (if predictable) design, near-standard 4K and 5K screens, and even better color accuracy than before. The 21.5-inch version is in some ways the more interesting of the two models, as this is the...

Apple iMac with 4K display review: small all-in-one gains a hugely impressive screen

 

The most compact desktop around just turned beautiful, and more useful too

Display ; Design ; Build quality

Fusion Drive not standard ; No height adjustability ; No discrete GPU

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

 

The 21.5-inch Apple iMac all-in-one steps up to a 4K display.

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.

Apple iMac with 4K Retina display 21.5-inch, 2015

 

The flagship device in Apple's just-updated late-2015 iMac line is the configuration reviewed here, stepping up to a gorgeous 21.5-inch 4K resolution display and starting at $1,499 in the US (£1,199 or AU$2,099). Two other base models, at $1,099 and...

Apple iMac 21.5-Inch With 4K Retina Display (2015)

 

With a new Retina display, the latest Intel Core I CPU, and faster memory, the latest 21.5-inch Apple iMac is a very attractive option if you're creatively inclined and have limited space and/or funds.

Bright 4K Retina display. DCI-P3 color gamut. New rechargeable wireless peripherals. Includes Lightning cable.

No discrete graphics option. Base hard drive is only 5,400rpm. Headset jack and SD card slot are on back panel.

Conclusion If you make your living through the lens of a camera, or you're a serious creative type, the 21.5-inch 4K Retina iMac belongs high up on your short list —especially if you want the hi-res display but don't want to pay for the 27-inch 5K iMac...

Apple 21.5-inch iMac with Retina 4K display review: All about the ultra-high definition

 

A new iMac range is here to woo you into staying with the desktop in 2015 rather than going mobile. If you are still wanting to be bound to the desk and go Apple then the iMac is certainly the way to do it. Going Retina is certainly worth the extra...

4K screen resolution in top-end model looks great, new keyboard, faster performance than predecessor

Slow 5,400rpm hard drive as standard, mouse uncomfortable to use, no post-purchase RAM upgrades, Fusion Drive limits flash to 24GB (down from 128GB)

If you are still wanting to be bound to the desk and go Apple then the iMac is certainly the way to do it. Going Retina is certainly worth the extra cash with this 21.5-inch model - delivering ultra high-definition 4K without breaking the bank.

Apple iMac with 4K Retina display (21.5-inch, Late 2015) review

 

Incredible display proves that good things come in small packages

Display ; Design ; Speakers ; Accessories

Fusion drive not standard ; Chunky display bezel

Apple's smallest all-in-one features a great design and fantastic 4K display. Just make sure you upgrade to the Fusion Drive (at the very least) for faster boot and resume times.

A Review of the Apple 21.5 inch iMac with 4K Retina Display

 

Superb color rendering with DCI-P3 color space ; Fast, powerful machine for most uses ; Beautiful design ; Wonderfully quiet, cool running ; Decent price tag ; 9.4 million pixels ; El Capitan OS X works great with 4K display

No HDMI connectivity ; Uses slightly older Intel processing chip architecture ; No discrete Graphics card technology ; Storage memory could have been more advanced

While we consider Apple’s 5K Retina iMac to be the superior machine overall, the new 4k iMac has plenty going for it and comes at a relatively reasonable price for a piece of Apple technology with such a superb integrated True 4K display. On the whole,...
