I don't buy a new Mac until there is at least a 27" iMac for a fair price. Ridiculous that there are so many iMac 27" users still using 10+ year old computers because they need a larger screen in an all in one.
Timmy may have juiced the stock price but he has screwed those that made Apple.

that is when Tim Cook was running the Mac operation. The larger than 24" screen iMac buyers didn't 'build" the iMac foundation and "make" Apple.
for 15-17" display "all-in-one" Apple sells the MBA 15" and MBP 16" in even higher numbers than the iMac ever sold.
The 'fair price' of the 27" iMac was a fluke of Apple (and Tim) herding folks who probably wanted an xMac into the the 27" iMac product. That additional volume reduced the panel price and kept the cost down for the ones who did want it. The Mini and 21.5" iMacs were kneecaps on procoessor options so if needed the performance and didn't have Mac Pro money ... the 27" was the only option.
That 'herding' factor is basically gone. MBA / iMac / Mini (plain) / entry MBP all use the same basic chip. Mini Pro / Studio Max are covered by the MBP 14"/16".
