My biggest regret is not loading my Late 2016 with more SSD. I've found 512GB to be far more limiting than I ever imagined when I purchased earlier this year. I recently tried listing it on CL as an attempt to get out from under it, but no bites. If I took it to Apple and demanded a new logic board with more SSD what would that set me back? LOL. I'm only half kidding... Seriously though, any super portable recommendations for external drives? I've got this little USB-C SSD enclosure but it can be difficult to work with when lounging on a couch or something.
