Is the ssd upgradable post purchase or soldered in? Update (06/21/2017) The 2016 Macbook Pro 13 with touchbar had the SSD soldered but the version with function keys did NOT have SSD soldered. Have they for 2017 now changed production to soldering for the Macbook Pro with function keys?
Just like late last years new 13" MacBook Pro with function keys, the SSD is removable! But it’s a custom part! So Apple is the only source at this time. So upgrading while possible is not likely, unless someone reverse engineers the part (like what OWC did for the older retina SSD’s)
