GIFT CARDS!
It just implies that they don'y know anything about who is using Android phones in the U.S. I only have my gut to back this up (after observing who carries Android for the past 2 1/2 years or so) but Android devs will be able to make so much more money once Google starts selling gift cards in retail stores.
Why? Metro PCS, Boost Mobile, and teenagers. My guess is that they're a large part of the Android user base that is very unlikely to link up a credit card to their account. They would however be great candidates to use gift cards bought for them on birthdays/holidays.
I swear if they don't do this soon, it'll only keep more and more developers from releasing apps on Android. /rant
