If I do upgrade, no clue, I need to see prices and features. Plus, the new keyboard and pencil will factor in. But there is so much unknown.
I currently have a 12.9 M2 2TB cellular. I am willing to "upgrade" (I love tech, so I have no qualms with a minimal upgrade). But I really need to know what we are getting. I have had both 11 and 12.9 in the past, and I could go both ways, but the price will be a big factor this year. I wouldn't pay for a 12.9 M3 if I could get a MacBook Pro for a similar price, eg $3000+ with keyboard. Since the screen tech should be the same, the only real decision will probably be size - handheld 11 vs laptop-like 12.9.
My gut reaction is to stay put, I have far more iPad than I will need for a long time. But...we'll see.
