In reality it's crap, no FUSE, some GUI programs simply don't run, upgrades can trash your install, sporadic development attention from Google, and my 2015 MBP is an order of magnitude faster (wish I'd sprung for the 16Gb version though).
The new MBP without a touchbar would be a great replacement but the Book 3 has caught my attention. Love to hear stories from Mac->Windows refugees.
