If you follow the news about mobile technology, you've read a lot about hardware, and about topics such as the wars between iOS and Android. But the truth is, when it comes to mobility, it's not about the hardware. What's really important are the apps. And so you'd do well to know what kinds of mobile apps are most popular, and what types will be important in the future. Earlier this year, a Forrester report, The State Of Enterprise Mobile Security, Q1 2014: Strategies Shift From Devices To Apps, made it clear that for businesses, interest in apps trumps interest in hardware. The report concluded: "At the end of the day, we may talk about mobile devices, but in reality it's all about the apps." In fact, the report found, apps are so important that employees are willing to pay for them with their own money if the apps will help them do their jobs better. The report found "Over 46% of people who use a tablet for work and 32% of people who use a smartphone for work purchased at least one out-of-pocket business application."
