I currently have a MacBook Air 13", 2014. It works really well and I enjoy it. However I am wanting to upgrade to a rMBP for the retina screen and increased performance. I was planning on upgrading in the next month or so, but with the 2016 rMBPs looming, I was wondering if it would be worth it to wait. I'm looking to buy refurbished. Anyone think it would be worth it to wait until the 2016 models are released and then available as refurbs? Would this be too long to wait?
