Re: Solder not Socket...
Excellent resale value? if you class losing £1000-1500 out the door, off a £2500 15'' Macbook Pro w/ touchbar. I don't see this machine holding the £1500-£2000 mark, in the secondhand market. Maybe Apple refurbs, but not fleabay.
Apple macbook user with an active backup strategy? Do they exist?. OK, iCloud for Photos, Time machine at a push, but that's it.
At least might push a few into action, after their first data loss / Coffee/Coke spill.
