iPhone and Web 2.0
Because I think of it as a Web 2.0 device.
Its only button is the Home button (note the browser-centric name), which takes you to a page, sorry, “screen”, that has a bunch of user-selected widgets, sorry, “icons”. Just like Netvibes or Pageflakes or Google Personalized Home or whatever.
And it runs a “real computer” operating system, Mac OS X, with a “real browser”, Safari.
That’s where I already saw laptops/desktops headed for most users. Now I can see the iPhone accelerating the process: people will have their iPhone, and also their “iPhone with a keyboard and a bigger screen” for when that’s more useful. People with two devices find life much easier when they both work the same way.
“One more nail in the coffin of the personal computer”, I gloat.
