Has anyone here been using iPad through out his or her undergrad course? I'm a soon-to-be business student, and I've got a budget of $2000. I initially thought about maxed-out rMBP 13" ($1699), but now I'm leaning towards the combo of MBA 13" base model ($1099) + iPad 5. MBA will be left at home to do assignments + store files, music and photos for iPad; I'll buy a decent 1TB ext HDD to store films. I'll purchase the Microsoft Office subscription on the MBA and thus the Office app on iPad is free. I'll bring the iPad to school and edit documents later when I reach home on MBA. Sounds sweet? Now, I'm pretty confused about which model of iPad 5 to select. Is 4G needed? Should I buy the 64GB or 128GB model? I have 10GB of music, 20GB of purchased apps and the rest should be devoted for films & school work.
