I currently have a mid-2012, 13-inch MacBook Pro with upgraded RAM. I have to return the computer to my school this year in early May. I know there has been a delay in the Broadwell and I was wondering if it's known when those MacBooks will be coming out? And now I'm also hearing about SkyLake and I'm wondering if it's worth waiting for those. What would you recommend I wait for? Will SkyLake be a big step up from Broadwell? I'm going to have this new laptop for a while and am trying to figure out what's best in the long run. Thanks!
