Basically I am looking to get an ipad. I have an iphone but feel the screen is too small and i browse the internet a lot so the battery always goes within a couple of hours. I want an ipad to carry with me to work, on the bus and train, plus use at Uni. I want the ipad basically for listening to music, browsing, watching movies occasionally and maybe reading books. Basically something on the go. I do have a Macbook Pro bear in mind. Should I get the mini or retina?
