My mid-2012 rMBP (i7 2.3, 16GB RAM, SSD) is still working like a champ in most areas, however I'm seriously thinking about making a switch back to Windoze if the new MacBook Pro doesn't blow me away. The biggest issue I have is connectivity - the highest resolution I can drive at 60hz is 3440x1440 - no 4k/5k options here. Also, both GPUs (integrated and dedicated) have seen better days. I think the next rMBP will have at least a couple of TB3 ports, which will give me the ability to solve both issues (4k/5k 60hz and eGPU). What about an actual OLED panel? There have been a couple of reviews of the new Alienware 13 laptop with 1440p OLED display, and they both say nothing compares to how the screen looks. The retina panel is what did most of the work switching me to OS X in 2012 - I was spoiled. I hope Apple doesn't get left behind in features when the 2016 model is released. I want to stay with macOS!
