What the person quoted in OP is completely disregarding is that not everyone is like him. He thinks specs don't matter. Fine, that is his right. But others do, which is why they need to at least be included.
From a certain point of view, if a person doesn't care about the specs, they may as well buy whatever is the most popular and the most shiny, and turn off their ability to think independently. Join the pack, follow the herd, buy what others tell you to do. You get the idea.
And yes, kjk, getting twice the RAM without paying any extra for it, matters to me. Why should I pass up an opportunity to get more without being asked to paying more?
