What stack are you using that you find the 512GB limit to be a problem? I've picked up one of the 16/512 MBPs and am wondering if I should swap it for a 16/1TB MBA, or maybe MBP but I have a little while to decide.
This is personal laptop - I've got >250GB in Photos which, even on "store originals in iCloud" mode takes up a huge chunk of the 512GB. I've got several x00GB folders in Dropbox that I can't currently have on the laptop (fonts, assets, etc.) 50GB+ in ~/git. I hover around 5-10GB free space these days.
