"And between these two giants, it will be no contest. Google will almost certainly have vastly superior search -- it's Google, after all -- superior messaging, superior office documents, superior spam filtering, superior video chat -- superior everything."<p>I think the author is drastically overstating the inevitability of Google's product superiority. Google already spectacularly failed once at messaging with Google Wave, and Gmail doesn't actually have the market share that most people think it has (even just considering webmail). Office documents don't seem to be a make-or-break feature for social, and Google Docs has had very limited success competing with Microsoft Office (in fact, my favorite Google office productivity product, EtherPad, was killed in favor of Wave). Spam filtering is legitimate, but it's not that hard of a problem really in a technical sense; Facebook could keep up. Video chat is a weak point for Facebook, granted.<p>Besides, integrating your competitor's product as a feature of your own doesn't always spell success. Microsoft integrated Bing with its operating system through the IE search box, and look how little that has mattered. Both Apple and Microsoft have tried to "feature-ize" Dropbox, and Dropbox seems to have emerged unscathed. Instapaper is doing fine even in the face of the Safari Reading List. The list goes on. (Sometimes the strategy does work, such as IE against Netscape, but it's hardly clear-cut.)
