Tim O'Reilly of O'Reilly Media is credited as the guy who came up with the term "Web 2.0." Turns out there's a Web 2.0 Expo, and who'd ya think gave the keynote address? (Three guesses, and the first two don't count.)
Anyway, Tim O. was discussing the Internet Operating System (his term for intertwined web services including searches, online/mobile payment, and the "social graph" of sites like Facebook) and how well major players like Apple, Microsoft, and Google address it. According to O'Reilly, Apple doesn't really get the concept of web-based services, focusing its push for "world domination" via a fully-stocked App Store. Google, on the other hand, absolutely gets it, in the way their disparate products knit together nicely (with Google Voice a "front end" for everything), regardless of hardware platform.
