Hi guys I'd like to buy a laptop complementary to a desktop workstation. I will use it when traveling, mainly to do some photoshop, backup 4K footage to an external drive, maybe some rough editing. I need maximum portability as my back already hurts so I'm not considering the 2015 models. It should be as lightweight as possible, but I don't know how heavy the 2017 MBPs feel in this regard. (I previously owned an early 2011 15" MBP which was way too heavy) I intend to have a Bootcamp windows partition and don't know if 256Gb will be enough. So... here are the contenders : 1/ Maxed out MacBook 12" (i7 1,4 GHz, 16GB, 512 SSD) (lowest weight) Vs 2/ Maxed out MacBook Air (i7 2,8 GHz, 8GB, 512 SSD) (MagSafe and ports) Vs 3/ Almost maxed MBP TB 13" (i7 3,5 GHz, 16GB, 512 SSD) (P3 display) Vs 4/ Stock entry MBP TB 15" (i7 2,8 Ghz, 16GB, 256 SSD) (Same price as MBP TB 13 above + Radeon Pro graphics) ???? Hope someone can help me choose!
