Because I think we're using two different definitions of obselete. Just because people will buy a thing years down the road, doesn't mean it wasn't already obselete then or when it was brand new or that those second purchasers can't make some use of it, however strained. I disagree about ram, at least at the minimum threshold, evidenced by numerous naive customers I've witnessed being incredulous as to why a few chrome tabs and some temp files are bringing their $1k+ computer to a halt.

Would you have bought a MacBook air or pro in 2017 with 4gb of non-replaceable ram for $1000? No, because it's obselete and you know that. What if they told you it was a great computer, and you didn't know anything about computers? Probably.
