I have a 2.6GHz quad core macbook pro retina with 8gb of ram and 512gb ssd and I was debating on selling it for school and getting a 13" MBA and a iPad air. I have an iPad 2 but I was thinking about giving it to my dad if I switch. What are your honest thoughts. I'll mainly be using it for business administration at my school. I used to build pc's and game on them so I thought I needed a lot of power but all I do now is browse the web and do some other stuff. Thanks!
