Google Play
I know that there is probably conflict between Google Wallet/Checkout - but they need to get on this issue like last YEAR -<p>GIFT CARDS!<p>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.<p>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 <i>would</i> however be great candidates to use gift cards bought for them on birthdays/holidays.<p>I swear if they don't do this soon, it'll only keep more and more developers from releasing apps on Android.
