Beyond search, Google Wallet may challenge PayPal
Google offers more and more services all the time. Check out Google Labs for a peak into one layer of what they are working on. See also XtraGoogle for a shortcut to many of Google's services and Soople for a graphic interface making advanced search queries easier to use. Wikipedia has a great entry listing Google tools that are available.
If you dislike Google's search hegemony (I know I do some times) you might enjoy Clusty, A9.com and Jux2 for searches. All produce very good results, as well as offering cool features that Google doesn't have.
Most interesting is his call for cooperation between Google and PayPal. Collaboration between services should happen far more often than it does. It's a real pain to use different Instant Messaging services, and I really wish there was more collaboration across tagging and social bookmarking systems. Can you imagine how horrid it would be if you couldn't email people who were using a different email service than you? I don't know why competitor cooperation is so rare still online, other than that companies are still stuck in an old paradigm of trying to lock users in to their service alone. It's ugly, and hopefully it's a paradigm that is dying in favor of services competing based on their relative merits.
