I think personal computers are still in transition, perhaps now entering their third generation. In 1980 they were toys of exploration used mostly by hobbyists and early small business adopters. In 2000 they became our portal to the world via web, social communities, and messaging. In 2010 they migrated onto mobile devices, but largely offered the same services as before -- at most generation 2.5. Having been there and done all that, the question now is, what comes next? But no Next Next Thing is apparent, especially for those who live to be wired. Personal computing has become a flat level playing field that extends to the visible horizon where the cutting edge user is no closer to the vanguard of tech utopianism than the Everyman who lives only within Facebook. And what fun is that?
