And then, through the network effect, my family followed suit because I'm their IT guy (actually, one of the reasons I quit Windows too, but they just keep dragging me back).
But the premium isn't too bad, IMO. I've had my current laptop (MBP, retina display) since 2012 and it's still going strong, even the original battery. I recognize that this is partially because we seem to have plateaued a bit on desktop/laptop capabilities, but I have no major issue running anything I want to run on it (modulo games, whicH I don't play so is a non-issue for me). I've also been able to reliably sell their laptops for a decent amount (could probably get more, but always sell to friends) and end up with a discounted new laptop as a result.
EDIT: Further, my experience with non-tech owners of Apple laptops versus PC laptops has been interesting. I don't know if the PC laptops are just more fragile, or if the Apple owners are more conscientious. But Apple laptops seem to last much longer and end up in much better shape (less the power cords) with "average" users. But this is purely anecdotal. A large part of that difference is probably just that a $1000-2000 PC laptop would last just as well as the same price Apple, but more PC laptop owners get the $300-500 sale price machines from Best Buy.
(This is me appreciating the enemy's skill from afar. I do not personally like Apple products. Just as I prefer wearing paint-stained sweatpants and 10-year-old extra-large t-shirts, as well as running linux on 8-year-old workstation. My favorite "smart"phone is a blackberry classic.)
