I've decided I'm going to buy a 13" MBP with touchbar after going a year without a laptop since my 2011 MBP dGPU failed but I'm not sure whether to go down the refurb route or buy new. Looking to get one with maxed out RAM and upgraded 512GB SSD. I can but a 2017 version for £2001 with health service discount on the Apple store or can get a 2016 version for £1729 from the refurb store. I understand the difference in real world performance between the Iris Pro 550 and the 650 in the 2017 model is fairly minimal especially for my uses, which are browsing, some light video editing, photography and photoshop mainly. Any other differences I should be aware of between 2016 and 2017 models? Also I've heard varying things about fan noise with some saying the nTB is silent compared to the TB version...is this true? Which would you go for...2017 or save a bit and go down the refurb route with the 2016 model? I've never bought a refurb product from Apple before so experiences would be great please.
