So I have. 2010 13" MBP. The computer itself works fine but we recently got a new iMac that is now the workhorse. The 2010 model does not have the ability to AirPlay mirror and when I took it to Hawaii. I could not play my 1080p 120fps GoPro footage that I captured. So I'm looking to upgrade to at least a 2012 model so I have the AirPlay option, but after 2012 the user upgradable RAM goes away. So which model should I get? Uses: When traveling to download and store photos and GoPro footage Run A/V at my church, music, videos, PowerPoint, record/edit sermons Anytime I want to sit on the couch instead of the desk I'm wondering if at this point a MB Air would suffice, but again, the GoPro footage is what would be the deciding factor. Anybody know the minim processor speed I need or what year I should be narrowing my search to?
