I'll be a pedant and point out that bit of hyperbole has a bit of an odd timeline issue. It seems to say he jumped ship to Android when the app store was announced. But iPhone OS 2 which introduced the walled garden app store came out before Android 1.0.

Plus, if you're so worried about things like walled gardens, why buy a phone that doesn't officially allow third party native apps like the iPhone with v1.x OS?
