What are the differences between original 15 inch retina Macbook (which I currently own) and current one? I thought the display was difference / better? I know the force touch went into the MBP in the Mid 2015 update. Also the SSD is faster now.. The current MBP I have is 15 inch and it isn't that stable and seems reload up everytime I turn it on and battery life is poor. Other then that I really like. I wondering if getting a mid 2015 model for $2K new on eBay is right option or waiting for skylake redesign? I don't think the skylake performance increase is all that much.
