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

 

If you are still wanting to be bound to the desk and go Apple then the iMac is certainly the way to do it.

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

 

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 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 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 iMac 21-inch review (late-2015)

 

Apple updates its smaller-sized iMac with a Retina 4K screen, and it's a compact all-in-one to be reckoned with

“Whichever of these you choose, however, the iMac has a positively prehistoric 1TB 5,400rpm HDD.”

iMac with 4K Retina display review: A high-resolution desktop Mac for the masses

 

The Mac is a small fraction of Apple's total business, and of that, roughly three-quarters of the Macs sold are laptops. Apple could probably be forgiven if it put the entire iMac line into maintenance mode: after all, sometimes it seems like that's...

Gorgeous Retina screen ; Thunderbolt 2 support

Fast flash-storage available as an option ; Hampered by slow 5200 rpm hard drive ; Discrete GPU available only as configuration option ; Uses previous generation Intel chipset

The 5K iMac is an incredible computer, one of the best Macs ever made—but it’s also just too much for many people. A 27-inch display can dominate a desk or a room, and though the price tag has come down a lot in the past year, it’s still on the pricey...

iMac 4K in prova, basta lo schermo per dare spettacolo

 

Apple ha rilanciato la gamma iMac inserendo nel nuovo modello da 21.5" uno schermo incredibile con risoluzione 4K, capace di coprire lo spazio colore DCI-P3. Un prodotto destinato ai professionisti dell'immagine, con prestazioni comunque adeguate...

Schermo di qualità incredibile ; Prestazioni comunque sorprendenti nonostante la scheda integrata ; Sistema operativo e ecosistema

Il disco tradizionale da 5200 giri non ha senso di esistere su questo computer ; Prezzo non indifferente, soprattutto con un disco SSD

Uno strumento di lavoro perfetto. Ma non è per tutti
