The issue about never have the perfect phone is a combination of the above and the fact that companies who develop and manufacture phones (not always the same for one and the same model) are in it to make a profit, and also have to take into account that at the end of a models lifespan it will be sold at a significantly lower price, but the goal is to still make a profit, so all this (and A LOT more factors) have to be taken into consideration.
