Looks amazing, and the speed boosts look significant (rather than just the usual incremental steps).
The 24" screen is a nice improvement over 21", and tempting. (21" was too small. 24" is acceptable).
But I'm disappointed they didn't offer a 27" version as well (or will it be 30"?). I've lusted after a large screen iMac for a couple of years. But I've been delaying the purchase for one reason or another for the last 2 years... and then Apple's switch from Intel to Apple silicon has added another year or so to the wait.
Hopefully the 27" (30"?) will come out in the autumn. Really wish I didn't have to keep waiting. But at least we're in the home stretch.
P.S. Still have reservations about a combo computer/monitor. It's a sublime when new, but a good monitor should last a lot longer than the computer. My current monitor (a high end 24" Dell 1920:1080) is over 12 years old, and still does a nice job. It's outlasted... 3 computers? Maybe 4?
And if I'm not mistaken you *can't* use an older iMac as an second monitor, right?
