    5.0 out of 5 stars A Fabulous Computer That I Enjoy Working From
    Reviewed in the United States on December 7, 2020

    First, I haven't owned at home a desktop computer since purchasing the original Navy Blue all-in-one iMac back in the Late 90's/early 2000's. Ive since only had Mac laptops like the MacBook Pro and MacBook Air. Since I am fortunate enough to be working entirely from home these days, I wanted something that not only preformed like a Formula 1 car but also looked beautiful and simply put: nothing can compete with this iMac. This is the fully loaded version of the 21.5 inch monitor.... the 27 inch was simply too big for me and I have to say, the 4k ultra HD Retina display does not disappoint. I work for a tech company that requires sometimes very high rendering rates and Im amazed at how fast and how good it looks on this screen. In addition, it simply looks beautiful sitting on my desk. I couldn't recommend this iMac higher. Ive been a fan since the beginning of the iMac and remember when Steve Jobs did the original Keynote announcing these to the world and 20 years later, Im happy to say the iMac is still the best looking and one of the best preforming desktop computers on the market.

    5.0 out of 5 stars Amazon's delivery process left something to be desired, but the seller and the product are excellent
    Reviewed in the United States on January 23, 2023
    Verified Purchase
    The computer does everything it's expected to do. Nothing surprising to say about it. But Amazon indicated that the package would require a signature on delivery. The delivery person simply dropped it at the door without even knocking, quite late in the day on which it was listed as 'Out for Delivery' (I waited around all day for it). I guess it's not Amazon's fault either, but a problem with that particular employee. But Amazon gives you no way (so far as I know) to complain about a thing like that. And that's on Amazon.

    Awesome computer. The high resolution display is so much better than my 2013 iMac. The SSD solid state storage is lightening quick. The old iMac had 1 tb hard drive. That was much more than I need and hard drives will eventually fail. They are spinning at 1000s of rpms. They will crash given time. I suppose an SSD can fail too, so I keep a backup of critical files. 256 gb of SSD storage is plenty for me. I love the rechargeable keyboard and mouse. Seemed like I was always changing batteries in the old keyboard and mouse. Love this machine.

    Style: 3.6GHZ Intel Core i3Verified Purchase
    I love the big screen and the crisp, sharp images. It is fast, delightful, and such a great upgrade from a 13 inch screen. But what is worse than seeing your high-end product actually doesn't deliver the promised beauty? I unpacked it with great excitement, and got back to work immediately. Opened my first zoom meeting only to see myself and my background in deep red/ pink tone! Everyone else was in their natural light/ tones, but I glowed like a traffic light! After the meeting, I tried the camera with the Photo Booth, but no change! I searched all the apple help channels, and followed all the steps that supposedly would solve the problem. None worked! When I saw similar complaints, I thought Apple must have already solved the problem with an update. I updated to new Big Sur, checked updates for Zoom, but it is still that super annoying red/ pink image on the screen! I had to set up a "genius" appointment for the earliest one, which is one week later, and I will have to take this huge screen with me, wait online and hopefully get help, which I am afraid will include everything I tried until they say "oops, product defect!". At least Apple should be different, more careful, thoughtful I thought! I am very disappointed!

    The New Apple iMac with Retina 4K Display (21.5-inch, 8GB RAM, 256GB SSD Storage) is wonderful. I was going to wait until Apple put the M-1 chip in the iMac, but i changed my mind and I am so glad I did. The display is beautiful and sharp. My last iMax lasted 8 years - I'm sure this one will as well and then on to the latest Mac!
