I suppose the answer is that an used macbook lose very little value. Last time I checked my 2008 Macbook is still valued 75% of its original price.

Your 2008 MacBook has already lost more in value than the entire cost of my Lenovo.

Unlikely, it was about 1100 euros, so actually changing it once every 3 years is about the same cost as switching PCs once every three years, except that in the meanwhile I'm using much better hardware, and without Windows.
