I wonder why people really don’t prefer iMacs anymore?

Photos are from Apple’s refurbished page. Many of the refurbished iMacs are haven’t still be purchased by anyone despite being available for a few months while MacBook Airs already becoming sold out a few days after becoming available as refurbished. There are even quite a number of M1 iMac options still being available as refurbished despite being 4 years old and being discontinued more than a year ago. On the other hand, the M2 Mac Mini, which got discontinued only 4 months ago already being sold out and no longer sold as refurbished. I wonder if people are really not interested on iMacs anymore and hence not willing to buy the colorful ones?
