Right.
If the larger iMac is, as usual, largely the same as the smaller one but with a bigger screen, I think they would’ve launched it this year. The 24-inch iMac already exists as the new mainstream iMac. The bigger one now serves a different audience.
That’s my headcanon anyway.
Type C doesn’t solve any problem. If you need an adapter to connect to a screen, just make it another Thunderbolt port. The whole appeal of having a HDMI socket is that any HDMI cable will just work.
Yes, and I already agreed.

You’re right, they should consider that.
