With my families iPods and iPads, we only have to buy an app once and it can be loaded onto all of our devices. That is because we all link up to the same account on iTunes. But with Android, each of us (me, wife and daughter) each have to get our own gmail accounts and I assume would all need to use that account to purchase apps. What is the best way to share the apps among our phones like I can with Apple stuff? Can I just purchase them on mine and sideload them onto theirs?
