You seem to keep making these assertions as if they’re fact, but reality is, they’re not. There’s absolutely no reason that Microsoft Office software on the iPad can’t run at feature parity with the Windows versions, or at least the Mac versions. It’s not because the hardware can’t handle it, it’s because Microsoft doesn’t want the iPad version to be at parity with the desktop version, likely (IMO) because that could threaten Surface Pro sales. Same with Adobe, Affinity’s suite of apps on the iPad are at near full feature parity with the desktop versions, in fact, I don’t even know which features it’s supposedly missing compared to the desktop version. I’ve used Affinity software for many years now, and I do all of my professional graphic design work on my iPad with the iPad versions of the Affinity apps. Adobe could likely deliver their iPad apps at feature parity as well, they just are slow on the uptake. These apps run very well, even on an M1 MacBook Air (or even older Intel powered MacBook Airs). An M4 iPad should be able to run them fine.
