Ipad or macbook for university

I’m thinking about studying English literature at university, but I don’t know which device to get. Everyone says, “you’ll write a lot so you need an iPad to write with the pencil. A macbook would be inconvenient and you can’t even read pdf’s properly on it” if that’s the case which ipad should i buy? Of course not the Pro it’s a bit too expensive for me. If i get the Air i can afford the 128 gb version but i dont know if it will be enough space for me since i’m only gonna use it for reading a book and writing notes but if i get the ipad A16 i can get the 216 gb one. However i’ve heard from some people that the Ipad A16 starts lagging after about a year of use. So which one should i go for? Or should i buy a macbook instead if that’s what i’ll really need?
