It really is naughty of you to convert "less and less relevant" to "death knell" especially after I've said that mobile doesn't need to displace PC to succeed. Oh, well. As long as everybody stays productive, we can review in a year and see what's happening.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
