I am going to be starting post-secondary school in a few months. Right now I have an iPhone 4, a iMac 21.5 inch, and I will be getting one of the Mac laptops for school. I am thinking of buying an iPad mini but am afraid that I will not find use of all my apple products. My iPhone will obviously be used as my phone, my laptop for taking notes in class and my iMac for my actual school work. My question is if I will be able to find use in an iPad mini when I already have all these other products, or will one of the products end up being unused?
