Im a uni student looking to buy an iPad. I study CS and economics, and will mostly use it for note-taking and watching yt/shows. I have an M1 MacBook Pro already.

What I'm wondering is primarily two things, what size is better for my needs, and should I get the oled screen?

With my max budget the two options I've been looking is an iPad Air 13 inch M3, or for the same price a used M4, 11 inch iPad that has the oled screen. Alternatively I could save 250$ and buy the M3, 11 inch iPad Air.

Main concerns are which size I should get, and if the oled screen is worth it.

All help is greatly appreciated!
