Cheapest 4.5K all in one I found was $3,500. Although it has the renowned Surface screen. It's really more in the league of the 5K iMac. Which the 5k iMac still has better pricing. But the Surface has a specific user design for digital artists.

Basically, all in one prices suck. Compared to the competition. Apple's prices aren't that bad. If not pretty good. Sure you can get some cheap one with a 1080p screen. But then you are comparing something with a $100-$200 panel against something with a $500 to $700 panel.
At $1300. Apple is selling a comparable computer to the $1,700 HP. Probably better than the HP. As the panel is higher end, the CPU is faster and it has USB 4. Although the HP is upgradeable.
While I'm not a big fan of the looks of either. I do think the iMac looks nicer than the HP. Especially with that reverse notch.🤮
