Super machine at good price

After Christmas sales are wonderful at Adorama. Just have to be alert and keep an eye for a great deal. Blink and it might be gone. This was a good after holiday deal. The great one got away the day before.

Good so far

Product wise, I'm not sure it's worth the money. I expected more for the cost. I don't t see anything great about the 4K monitor. Only time will tell if it was a good buy. We have not had any issues with it. Shipping was fast and excellent.

Get the fusion drive!

I bought this to replace a 2009 27" iMac. While I miss the larger screen real estate, this machine has features that more than make up for it. The clarity of the 4K display is great for editing photos. I opted to max out the RAM as it is not user upgradable. I also chose the fusion drive as I wanted a machine which was quick to start up, yet has a large rotation drive capacity at only a small price increase. I couldn't be happier with the speed of booting and lsunching applications. I also ordered the external SuperDrive as I like to rip music and DVD's to import into iTunes. My only complaint was the included wireless keyboard. I tried it for a week before going back to my larger wired keyboard. I feel the wireless keyboard is too flat and doesn't provide enough feedback. I'm sure this iMac will give me years of great service.

Great display and typical Mac ease of use

I bought this machine to replace a six year old imac. In many ways, it is identical, but the retina 4K display and the much faster processing time make this new one a real pleasure to use. It doesn't seem to want to recognize my external Verbatim time machine, which is annoying, but I am sure that a call to tech support will help me fix that problem. Otherwise, no complaints.

Outstanding Value for an Outstanding Product!

I was looking around for the best price on a very nice Apple iMac 21.5" Retina computer and having trouble finding the right setup. Then I checked out Adorama where I have considerable luck before and sure enough, they had the exact model in the configuration I wanted. My Apple 21.5" iMac Retina comes with 8GB of RAM and a 256GB SSD. The SSD option is what tipped the scales for me and I thank Adorama for giving me the choice to select my own configuration. No other place that I shopped had a "build-your-own" option and that sealed the deal for me. Shipping was fast and excellent. I like that I have to sign to receive the shipment. At these prices, positive control of the delivered product is essential. I will definitely be buying from Adorama the next time I'm in the market for a new Apple computer or just about any other electronic device. Their prices are super and service is excellent.

Love the iMac, my 2nd one!

Already had the iMac 2010. Filled it up. Honestly, I don't see this display as that much different, both are awesome. 21.5 is fine for me, but if I had the room I would get the larger display, not much more money. Upgraded the ram & fusion drive. Very fast, smooth. iMacs are all I want any more. Adorama is so easy to deal with, & saved me about ($) over Apple store.

With an external ssd for startup this is great

The screen is great and the processor is fast. I set it up with a thunderbolt ssd to boot Mac OS and Windows the day I got it.

This computer is amazingly fast. I have been using an obsolete, eight year old, 17" Macbook Pro which is very slow compared to this computer. It's a joy to use. Adorama was very good to deal with. I believe their price was the best on the internet.

Great machine

This iMac replaces a four-year old 13" MacBook Pro (non-Retina), with which I'd begun to have some difficulties (age, I am certain, played a role). The IMac is so much quicker and the Retina display make everything easier to see work with. Totally dig this machine.

Nice upgrade

I bought this computer as an upgrade to an older MacBook Pro and am very pleased with the great picture quality and speed increase over my older computer. I would definitely recommend this model for anyone wanting a top of the line iMac. I do a lot of photo processing so having the faster processor and increased ram was a necessity for me.

Very nice system !

I had a Window desktop, iPad and iPhone. Decided to become a complete Apple household and have no regrets. iMac 21.5 works great right out of the box. Beautiful display. All I have to do know is learn about all the nice features that of the OS.

Love my new iMac

Now that I've gotten my files migrated from my 2008 MacBook (easy once I used a remote HD to back up and then upload). It's fast, sleek, smooth and the 4K Retina screen ... fantastic! I just viewed Adele's video "Hello" full screen. On my MacBook it was good. Here it's absolutely fantastic. The resolution, sharpness, vividness is stunning and worth the price. I opted for a 256 GB SSD as I never again want to see the spinning wheel of death as a drive tries to pull up files. Had I little more $$ I would have opted for at least a 512, but SSD is the future, the standard HD is the past. And I have a 1TB remote HD for storing old files and photos. I don't know what else to add other that this computer is stunning. And my files, programs and documents migrated completely, even my screen saver! I had to wait about 2-1/2 weeks for delivery, but I reaiize my configuration is not the a standard one. I was patient and it was worth the wait. Product arrived safe, sound and just as ordered.

Fills a special role in small office

I needed an iMac server for a heavily used database. My employee will be staring at this computer seven to eight hours per day. The 4K display, the silent flash drive and the performance options should fit the bill nicely.

Retina. Now in colossal and ginormous.
The idea behind iMac has never wavered: to craft the ultimate desktop experience. The best display, paired with high-performance processors, graphics, and storage - all within an incredibly thin, seamless enclosure. And that commitment continues with the all-new 21.5-inch iMac with Retina 4K display. Like the revolutionary 27-inch 5K model, it delivers such spectacular image quality that everything else around you seems to disappear. Adding up to the most immersive iMac experience yet - and another big, beautiful step forward.

More than just a display, it's a vision.
Accuracy. Brightness. Clarity. Regardless of how you measure the quality of a display, Retina is in a class by itself. The pixel density is so high that you won't detect a single one while using iMac. Text is so sharp, you'll feel like you're reading email and documents on a printed page. And with a new, wider color gamut, the Retina display is able to deliver even more available colors 25 percent more. So every photo and video you see appears even more true to life.

For the 4K camera in your pocket.
The new iPhone 6s shoots gorgeous 4K video. And on iMac with Retina display, both iMovie and Final Cut Pro give you the resolution and responsiveness to edit in 4K, turning your footage into a phenomenal viewing experience.

Design - Innovation from edge to cutting edge.
An incredible amount of engineering was required to bring the Retina display to the iMac family. Witness a design that's just 5 mm at its edge yet entirely capable of making everything around you fade into the distance. This ensures that nothing gets between you and your favorite content. Seamless and beautiful, iMac with Retina display is an elegant addition to your workspace, representing a depth of technology at the height of design.

Built for speed. And everything else.
The 21.5-inch iMac features a fifth-generation Intel Core processor and enhanced Intel Iris Pro Graphics. It delivers stirring visual effects with maximum impact at maximum speed.

Redesigned. Rechargeable. Remarkable.
The all-new Magic Keyboard, Magic Mouse 2, and Magic Trackpad 2 have been redesigned to make every interaction feel amazing. From a built-in rechargeable battery to a new lower profile, they've been enhanced to deliver more comfort and functionality than ever before. Paired with iMac, they work magic together.

Magic Keyboard
Redesigned with a lower profile and increased stability that makes typing with precision a breeze.

Magic Mouse 2
A new design gives our Multi-Touch mouse a solid build and a smoother glide for quality you can feel.

Magic Trackpad 2
Now with Force Touch technology that lets you press a little deeper on a larger, click-anywhere surface - and do a lot more.

Fast connections for high performance.
iMac is astonishingly thin. But it's jam-packed with advanced technology. Two Thunderbolt 2 ports come standard on all iMac models and deliver blazing-fast data transfer for external drives and cameras. Four USB 3 ports give you plenty of options for connecting peripherals, including your printer, video devices, and more. And with ultrafast three-stream Wi-Fi and Bluetooth 4.0 wireless technology, you're instantly connected to all your favorite content.

The world's most advanced desktop operating system.
The Mac OS is what makes a Mac a Mac. Not only is it designed to be intuitive and easy to use, but it's also engineered to take full advantage of the Retina display, so you'll see everything on your desktop with stunning clarity. It features an incredible collection of apps you'll use and love every day. And it's designed to enable your Mac and iOS devices to work together in amazing ways.

Our best built-in apps. The best they've ever looked.
Every new Mac comes with Photos, iMovie, GarageBand, Pages, Numbers, and Keynote. So you can be creative right from the start. You also get great apps for email, surfing the web, sending texts, and making FaceTime calls there's even an app for finding new apps.

iCloud - Everything you love on your iMac. On all your devices.
iCloud stores your content and lets you access your music, photos, calendars, contacts, and more from whatever device you're using. And with iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images, and any other kind of document in iCloud and access them from your iPhone, iPad, iPod touch, Mac, or PC.
