I have the 4th gen (2020) iPad Pro with the A12X Bionic, the same chip they put in the Apple Silicon transition dev kits. With iPadOS 26 it's become barely usable, despite still being performant as ever on iPadOS 18. I'm talking huge drop in performance, stutters and slow downs everywhere.

I was considering just replacing the battery and keeping it for several more years but now I feel forced to upgrade which has me considering whether I still want/need an iPad since I'd also have to buy a new magic keyboard since they redesigned it, and they bumped the price ($1299 now vs. $999 when I got the 4th gen) so I'd be looking at $1700. Trying to hold out for an iPad Air with ProMotion.

I may be in the minority here, but I think 5 years is too short of a lifespan for these devices at this point. Early days when things were advancing like crazy, sure. But now? I have 8 year old computers that are still just fine, and with the M-series chips I'd expect at least 10 years of usable life at minimum (battery not withstanding)
