That’s a fantastic point, but I can also think of two more. Let’s say you were thinking of an M2 but knew this was coming. The difference between the M3 and M2 may tell you it’s worth getting the newer M3 or the (now cheaper) M2. Or perhaps you saw the M2 wasn’t a big leap. You want to replace your older laptop but didn’t want to get an M2 because it wasn’t a big leap over the M1 in many respects. This info would tell you if it was a big leap (buy now!) or you might as well hold off another year if you can. The other reason is simply making it interesting. If every article was comparing to a 5-6 year old laptop, the answer would almost always be “it’s amazing!” Even if that’s what most people come from it’s a boring story. But year to year variation is much higher.
