Hi! I'll be going back to college and i'm looking at potentially going iPad only. I bought a 2016 15" MBP and I always use my iphone X. Literally never use my MacBook. I browse the web and use Khan Academy and listen to Music and browse social media. My only concern is old legacy software because i'd be taking my courses online. Like how i'd upload a file, etc. It'd be for a business major if that helps at all. I only have money for one Machine and I don't have any other computer. So should I keep my MBP and get an iPad sometime down the line or sell my computer and get the 12.9 with cellular. I'd really love to be able to go iPad only but again my concern is with things like university login software etc
