Does it matter if i have a physical or electronic textbook for college?

Hey guys,
So college is starting next week, and i already have an assignment (my English teacher told us to read 2 articles that we might have a quiz on it the first day). And my other classes i have to buy all these book, one of them was like $180 on ebay. So i thought well throughout my live i never really bought music CD or videos games, cause i just pirate them online. So i thought i should do the same save up some money. Only problem is idk if its better to have the textbook itself or and electronic version, like do teachers mind whether you have the text book on your ipad or laptop in class. And can anyone tell me what the pros and cons are for each of them (physical or e-books)
Added (1). ok, just so you know am not buying the e-book am just gonna download it from piratebay or something. ( I just don't wanna spend money) and if i have to get a physical text book i would rent one, but i won't be able to mark stuff in it i guess.
