I have had the nTB and TB both 512gb. I have also had various issues with screen uniformity, cracking, dodgy buttons so had a few replacements. I currently have the nTB but only 256gb as that's what they had in stock. I will struggle with 256 (tried to use iCloud to offload a couple of things as I have the 200gb plan) and the screen has a pink hue in the left hand corner plus there's more clicking. I can get the rMB M5 512gb for the same price @£1299 from JL with a 2 year warranty. I only really use the machine for word docs, media consumption etc. I don't connect to an external monitor and use the machine on my lap/sofa/bed. The 256 nTB cost me £1300 from Apple. Do I give up on the 16 MBP, buy the 16 rMB and hold out for the 2017 MBP as I should get a good resale price on the rMB?
