I'm considering purchasing an iPad in the upcoming refresh. I am a student so I would like to save as much money as possible. My university provides unlimited cloud storage through Box. This is how we access ALLL of our coursework. If I used my iPad and Notability/OneNote or something for reading pdfs/ppts, marking up, and saving again online, does it take up internal storage? I want to see if I can get away with just the base amount of storage, whatever that may be. I will be having no games, music etc on this device, it will be used mostly for school/medical apps for the clinic. of course, i will be grudgingly pay more, but only if needed!
