1) Do you use its native resolution and default macOS font size or have you changed one or the other (or both)? If so, why? 2) How far are your eyes away from the display? Please measure, don't guess ;-) 3) Do you use an external monitor as primary display? If so, why? 4) Do you find the size of the 27 inch display of the iMac too small, just right or too big? ... For me, the answers are as follows: 1) Yes, but I'm still undecided and sometimes wish some text was larger (e.g. in the menu bar). 2) My eyes are almost exactly 27" away from the display. 3) No, but in a few days I will try to use my 31.5" monitor again and check if I prefer it or not. 4) I would pref if it was larger. I guess I would like 30" to 32" the most. Before I bought my 27" iMac, I used a 21.5" iMac together with a 31.5" monitor, which was my main display. However, I was intrigued by the thought of having a minimalistic setup with just one device. Also, I had the epiphany that sitting 27" away from a 27" display makes it look just as large as sitting 31.5" away from a 31.5" display. I guess many people would find sitting just 27" away from the 27" iMac too close, but for me it feels right and has therefore become a rule of thumb to sit as far away from the display as its diagonal. So far, I like my minimalistic iMac-only (plus speakers) setup, but I am still getting used to having less distance to the display than before, which makes my desk look a little less wide. I am looking forward to your answers.
