Hey y'all I'm contemplating a purchase soon and have reached an impasse. Should I opt for the Mac mini quad core or a refurb rmbp 13in with 8gb or ram and a 128gb ssd. I like that I can modify and upgrade the Mac mini yet I'm drawn to the Pros retina display and portability also the pros very powerful. Any thoughts and advice are welcome. Also the mini would be purchased with a fusion drive so the cost will be very close in the end.
