ContributorNetwork – There’s a glut of tablets powered by Google’s Android operating system right now, as unsold inventory piles up on store shelves and in warehouses. And while analysts like IDC have reported that Android accounts for about a third of the global tablet market, Google’s own statistics about how many devices of what kinds have been activated show that very few Android tablets are actually in use. Especially compared to the iPad, which has sold almost 30 million units so far.
