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.

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 21.5-inch iMac with Retina 4K Display (2015) review: Display dazzles, but options are fewer

 

The 4K display might be something of a luxury for business users who simply want to run Microsoft Office, but the latest top-end 21.5-inch iMac will be an attractive option for users who need a fast and versatile desktop computer.

Bright, colourful 4K display ; Broadwell update provides strong processor performance ; Slimline, all-in-one design

Slow hard drive ; No longer includes discrete GPU ; Limited upgrade options

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

 

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.

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 iMac 27in 5K review

 

Apple's 5K, Kaby Lake iMac is here - and it is gorgeous

Excellent graphics performance; Sharp and vivid screen; Beautiful design

Fusion Drive lags behind SSD; Hard to access ports; Large screen bezels

The latest Apple iMac is a thing of beauty. Not only does it look excellent, it's got sterling performance and an absolutely first-rate display. If you're an artist or designer, you need this in your life.

Review: Apple's 21.5-inch iMac with 4K Retina display is great, but skip the slow HDD model

 

Apple's marketing team didn't need to dig deep to dream up a campaign for the new 21.5‑inch iMac with Retina 4K display -- its best feature is in the name. The stellar ultra high-resolution screen mates well with Apple's chosen internals, but it...

4K Retina display with P3 color gamut ; Powerful internals ; Small footprint

5,400 rpm HDD is a snail ; Price borders on 27-inch 5K iMac ; Slight backlight bleed at screen periphery ; Apple prices the new iMac with Retina 4K display at $1,499 for a baseline model and scales the line up to $2,399. Fortunately, a big part of what...

The 4K iMac's main draw is its gorgeous Retina display. For desktop users interested in having the best display around, the 21.5-inch 4k iMac is an easy recommendation with one caveat: it needs the HDD upgrade. An SSD would be preferable, obviously,...
