Given that you took the time to reply, I’d say my message found it’s mark.
Seriously, this is for once “The Best iPad Ever.” The OLED argument has been had for ages with monitors, phone screens, Nintendo Switch, SteamDeck, etc….those who really value the best screens go OLED. Those who are OK with good, but not the best, screens don’t.
My first OLED device was 8 years ago, Well before OLED even become affordable for most people. So i'm very familiar with OLED. Yes it's the best picture possible but it still has issues.
That one device I had eventually had burn in, just after the warranty expired. The device all of a sudden became worthless, as in worth almost nothing because of the defect. I literally had to sell it for peanuts.
Burn in on OLED is still a concern. Give it some time after the M4 iPad honeymoon passes. In a year's time or less, we will hear all about people who have the M4 iPads and spent thousands and thousands of dollars on it. Only to have burn in and their device is out of warranty.
Try selling any display device with burn in, I wouldn't want to be one of those people again. You get almost next to nothing for it. I've been in those shoes before and I'm not willing to risk wasting money again. I'm willing to pay for a much brighter screen but not an OLED screen.
Especially on a device that is one already overpriced and two something I don't need. Whereas regular LED tech is bulletproof at this point. That would explain why none of my computer monitors or my laptops or TVs are OLED. And I have over 10 display devices.
And again if I was to buy a new iPad today, I would either get the new air. Or I would get the M2 iPad pro mini LED and save a good chunk of money.
