Didn't LG just showcase the next generation of Ultrafine displays, including a OLED version? Maybe these will replace the ones not listed in Apple Store anymore.
Others commented already, but the PC-oriented side of the UltraFine line typically isn't quite an apples-to-apples offering (pun intended.)
Those other offerings have offered less pixels per inch than the Apple-targeted ones. I didn't look too closely into the new OLED version's specs, but it is a 4K offering across ~31.5 inches compared to 4K over 23.7-inch or 5K over 27-inch.
All they really need to do is take the rumored redesigned iMac, rip the computer out of it and boom, Apple display. A second display for the new iMac that lines up perfectly would be something that Apple has never done. It would also be perfect for the Mac mini, especially if they could keep the price under $1,000.
It would actually be interesting if the lowest cost iMac offering could just double as a display, having the flexibility of the old target display mode iMacs of old. Give this "SE" iMac the base model entry-level MacBook Air (or even AppleTV-esk) specs, but set it up such that the more powerful spec'd machine is in control. Or heck, maybe it runs an AppleTV derivative for AirPlay support.
I doubt an all-in-one M1-Lite chip would cut into margins significantly on a USD$1300 display, since it needs some computational hardware anyway. Especially if that same silicon was being shared across other products and being produced in high volume.
I considered the ultrafine, but considering the price I decided to just get a used 5k iMac instead. Very happy with my decision - nothing really compares to the 5k display.
Great choice. In my case I do have both an iMac and UltraFine side-by-side and it very nice to have the matching panel across both. The external monitor also provides me some display flexibility for a MacBook which I need to use for certain work – but while still enjoying the iMac-like size and resolution I'm used to.
I'll admit that with an iMac and the second 27" side-by-side (driven off the iMac), it is often too much screen when focussed on a single task – I'll find my head has been focussed on one for long stretches of time. So I can see why you'd be more than satisfied having just gone with the iMac. It is only when I'm suddenly referencing complex content (or switching regularly between two contexts, like a meeting I'm only partially needed for) that it suddenly feels extremely useful to have both again. Of course the use cases with the MacBook also provide extra utility for me.
Probably the improved resolution, but I've worked off of two 27" displays in the past and didn't feel like I'd get as "lost" in a single display like I do now. Weird.
