1000% disagree with everything said here.
Even without the UI changes, iPadOS 26 (or as I prefer to refer to it now Darwin 25, because I do think the name change is dumb) iPadOS is completely different and more useable for me. How are you guys only seeing photos app changes? Theres literally the 3 traffic buttons from Mac OS now. A menu bar, which will get more useful when 3rd parties start using it. It’s already nice having the standard stuff like copy/paste, etc up there. That alone is the best thing to ever happen to the iPad. So, yeah I don’t understand the complaints here.
Secondly, the glass UI is a much welcome needed change for me. I absolutely despised the post Yosemite flatness I’ve been cursed at starring at for 13 years. Dark mode helped but to me it was a bandaid over the ugly flat kindergarten UI. I hated the flat look on macOS, and I hated it with Windows 8+. Aqua and Aero should’ve never left. For some unholy reason I know there are people who disagree with, but I will die on this hill. The new UI is great, albeit buggy. We’re in dev beta 3, it’ll get better.
I’ll also mention that (at least on DP1 and 2, I just installed 3 as I was typing this so I haven’t had a run of it yet) my 11” M1 iPad Pro has much better battery life than it ever did on 18, or even 17. I mostly use my iPad in a place I can have it plugged in, so battery life isn’t a massive deal for me as it is for most people. But, surprisingly it improved with 26.
