What you really care about here is not resale value but "depreciation" curves.

Traditional PCs kind of depreciate like cars: you get a massive hit at the beginning, but then relatively slow depreciation there on out. Which makes buying second hand a better choice.

Macs depreciate kind of like buildings, slow at first, then it falls off a cliff (around when Apple drops support in the latest OSes), but then slow depreciation again.
