That's bollocks. Time Machine performance over network is atrocious.
With a HP/Dell Enterprise line model all you need is a decent set of screwdrivers (and if you're touching anything that requires taking off heat pipes, skme thermal paste) and you can literally replace any part in a hour or two from a spare laptop - or you just swap the disk in a spare.
With Apple's newest shit you can't even do that since everything is soldered.
I'm a die-hard Apple fan, but for large shops professional machines are lower in maintenance cost.
It's been awhile since I was in a big org, but when I was, no one was replacing laptop parts. The deals we had with Dell/HP were basically overnight replacements (this was different from servers where we had 4 hour on-site support). Then we would send them broken machines that would eventually come back fixed.
So do big orgs actually have people internally swapping random parts in a laptop to see if they can fix it?
Doesn't change the point that Apple was more expensive, but mainly because Dell/HP prices go way down at volume.
