I'm coming from a windows laptop and this will be my first Mac. Several negative reviews of the 2016 have me leaning towards the 2015 13" (i5, 16GB, 512GB)...what concerns me most is reports of the non-responsive touchbar issues, and graphics issues. I'm also worried that the touchbar will one day crap out on me, and it won't be covered by the warranty (first gen problems). The 2015 seems like a safe, reliable, and still powerful choice. However, once everything goes full on USB-C...will those of us that are on obsolete ports be left out?
