This 27" iMac replaces one I had for 10 years that was still working but kept having kernel panics from old software that I didn't know how to remove. Of course, this baby is lightning fast, and I like the Mac substitutes for Microsoft Office that I didn't have on my old computer. It was a little frustrating at first to get it to look the way I was used to. Then Big Sur wanted to be downloaded, and I had to make a few more adjustments. The weirdest thing I had forgotten maybe?? was how teeny the password box and everything else appeared until I figured out how to make everything appear bigger. I guess I did that 10 years ago, but I was surprised I had to go through so many settings to make me happy. Now I'm all set, and I couldn't be happier. I did buy a slanted holder for the keyboard; it was too flat for me since it's now rechargeable instead of having a battery compartment elevating it in the back. I can't imagine anyone not liking this computer. What's not to like (well, except the $$)? Hope this one lasts me 10 years, as well.
