That's not a matter of thickness but of TDP. The 1050 uses more power than the MBP can accommodate without a dedicated charging port. And a dedicated charging port is only needed if you're eating up a lot of battery power too, which isn't what the MBP is about. Not to mention the additional heat and noise.If the case of the MBP was 2-5mm thicker and A. did not use AMD (Pros use Cuda more often than not) and B. could accommodate say a GTX 1050 TI, I'd be thrilled. But that's just me.
