While users of each of the two major mobile platforms debate each one's merits and issues, in one aspect of comparison there is a clear and unequivocal difference between Android and iOS: Apple has a serious advantage when it comes to having its userbase all on the latest major version of its smartphone and tablet OS. A new study by mobile ad and market analyst Chitika shows that an astonishing 92.7 percent of iPhone owners are using iOS 6 as of June, while 82.9 percent of iPad owners are also using iOS 6 -- far ahead of Android users on OS 4.1 or later ("Jelly Bean").
