Nice strawman. First, no one has a "need" for this 12" Macbook over something similar. They might prefer something like this laptop, but there are similar, cheaper, better alternatives, and there's no excuse for Apple to have made so many ridiculous compromises. It could have been a perfectly good laptop, but Tim got carried away with the obsession on profit margins.
You have zero need for a pickup, but if someone said they were going buy a crippled, slow, one seater, low towing power, low capacity, soon to be obsolete, pickup; that also required additional pricey truck dongles to be able to use effectively; and that's also priced similar to a full featured high-end luxury car, I bet you wouldn't go around defending such a purchase. You would rightly criticize such a pickup and tell pickup buyers to identify the flaws and look for better, similar, price appropriate alternatives.
