Android die-hards can tell you everything that is wrong with iOS7, Apple’s recently released operating system for iPhones, iPads and iPods. Those who gripe every time something changes are also among the early detractors. Everyone else—that is, those of us who’ve gone back for a second or third helping of tasty iKool-Aid—loves it. The exclamation that I hear most often regarding the new iOS is, “It’s the same phone, but it seems like it’s brand new!” What struck me even harder than iWorship last week, however, was recounting the number of individuals who, with unchanged exteriors, have undergone noticeable overhauls in their Personal Operating System (POS)—for the better.
