I am a Mac Evangelist so am fully in the Apple Ecosystem.  Bought the 512 SSD version with i5 chip for $90 off and then another $60 off getting an Amazon Direct card.  So for me it was all about the best price on the new iMac.  My son with special needs loves it and faster than our 2017 iMac 21.5" with normal hard drive.The graphics and speed are excellent though I will say the 27" is a huge screen with excellent picture that I am not used to since usually on my MacBook Air 13"
