In the K12 computer space I always found it was cheaper to buy Apple devices for my users. Both from the fact that those devices did actually have less problems and lasted longer and so required less human monetary investment, but also an actual cost perspective since a MacBook Air could be bought for $800 after education enterprise discounts. Which was a much better than most devices in that price range (this was like 2018).
And in a world where HP exists you say the shittiest computer brand with dell?? (I work in tech sales now and I always joke with first time customers that they have to tell me their brand preference first since everyone in IT has a preference of devices between Dell, HP and Lenovo.)
