I would pick iPad 9 per your noted purpose unless you want better screen quality, speakers and processor.I really need an advice on this one please.
I just want a media iPad (for wacthing something or reading a book) which will NOT get used every day, it will not be a daily driver, it will not be there for any work related stuff. Alone for that I guess the iPad 9 would be the better choice, right?
The difference between the two where is about 200€ which is a bit much already.
I just fear that I kinda going to regret it because of the better display and better speakers (for the rare situation that I am going to watch a movie on it for example)
I already own an iPhone 14 Pro Max if that may be relevant for any reason.
