I've noticed that (in Australia at least), a base 2015 rMBP with 256GB SSD costs more than the base 2016 MBP (AU$2,319 vs AU$2,199). In the US, the price is identical ($1,499) Apart from the difference in ports & maybe the keyboard (which depends on personal requirements & preferences), is there any reason why someone would choose the older machine? It seems that Apple has priced these to actively discourage people from buying the older machine. Given the improvements to the MBP SSD speed, CPU, graphics & screen in the newer model, I think there is very little appeal in the older machine unless you are dongle-phobic. I would have expected the older machine to have a substantial discount, but this is not the case!
