His four main points are: openness, momentum, cloud, and capability. Android is definitely more open than iOS but Android's power depends on non-open software/services (Google). Android definitely has momentum but at their current rate it will still take years to match the iPhone's share of the market. Also, the Android app economy appears to be much weaker due to a cultural issue (rather than critical-mass issue). Cloud is a bit misleading as you can integrate Google's services with an iPhone almost as well as Android and iOS/MobileMe probably matches Android/Google albeit with a increase in cost and perhaps privacy. Capability is balanced by lack of usability.
I still think people are excusing flaws in Android due to frustration with Apple, hoping for "open" to win, etc.
I recently tried to switch to the Nokia N900 (Maemo OS, soon MeeGo OS) but found its capability did not balance its lack of usability.
