Gates's vision -- and failure thereof

"Bill Gates just gave a talk at a Gartner symposium where he predicted that hardware would get so cheap as to be essentially free. This is a pretty visionary idea -- and, I think, plausible enough; you can buy a $0.99 singing greeting card today with more computing power than all the world's digital computers at the launch of Sputnik (multiple Soviet space-programs' worth of cycles for under a buck!), so the idea of powerful, useful hardware going ubiquitous and cheap is pretty nifty and pretty credible."
