Kevin, I still think that OS is going to become a server-only issue invisible to 99.999% of people; the rest of us will use phone-sized devices and micropayment subscriptions to various applications to do most of what we need.
It's already started in Japan, fwiw. Kids with bluetooth (or similar?) phones walk up to a screen at school and hey presto, they've got a workstation. Their own workstation, just the way they like it. It's no wonder that PC sales are declining over there.
"... 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
