This is iMac 27 inch 2020 model with 5K display, and I upgrade the memory from 8GB to 128 GB, but looks I do not need such big memory for routine work. Anyway, the big the better.The display is brilliant, and the screen size is big enough to read ebook. My daughter used iPad to read ebooks, but the font size is a little small especially when two pages on one screen, so after I bought this 27 inch model, I created an account for her to share this computer, and she loves it so much!I also use this iMac to work from home, and the computing performance as well as the large screen is better than the laptop which makes work more efficient.In general, this is great product for home whatever for study, work or entertainment.
