Looking forward to this - made a mistake last time and didn't get the cellular model, so no GPS in it. OLED will be nice, and looking forward to the landscape camera.
My wife's got the 12 and is looking forward to switching back to the smaller one - both because of weight, but mostly because of the blooming issue on the screen.
And these ipads are likely to be 4 year devices. All of our apple purchase cycles are extending towards that because the devices are all well into the good enough (or better than good enough) category, and it takes multiple years of refinements to hit the 'worth it' threshold.
Apple Silicon changed the game across the board. With the new ipads, all other little refinements are about all in place. The last major one on the phone is the lightning on the 14's, but that alone isn't worth upgrading until the 17's. Ditto the M1 MBP's - M4 is the target, and even then it'd have to have TB5 and Wifi7 to really be a trigger. Ultra watch is about the most perfect device apple's built yet (as long as they stop nerfing the UX with WatchOS upgrades that is), and barring a major new health sensor (that's actually FDA approved and unencumbered by patents lol), I can't see why I'd upgrade anytime soon.
