I wanted to address his third point, productivity. Android is sorely lacking in productivity apps, and some enterprise technologies (Cisco IPSec VPN). Unfortunately, while the iPad is improving, its still pretty weak in that area. Of the 225k iPad specific apps, there are only a handful that try to replicate the complexity of a desktop app. Most apps aren't that ambitious. Omnigroup deserves special recognition--OmniGraffle, OmniOutliner, OmniPlan, and OmniFocus, are full scale applications. Apple, of course, has the iWork apps plus iMovie and iPhoto. And there are some others--Diet Coda, Photoshop Touch, etc.
