Laptops are more vulnerable. They are more likely to need replacement fans, new display, new keyboard. For a mainboard upgrade, it might make sense if two generations ahead is seriously better. For example, 13th gen i5 is outperforming the 12th gen i7. The i5 mainboard costs 450$ and the i7 1000$, so if you can wait for two new generations it would be worth it.
