An increasing number of business executives and corporate companies are replacing their BlackBerry smartphones with iPhones, thanks to the belief that Apple's device provides a more user-friendly experience.

Moreover, iPhone is challenging the dominance of BlackBerry by providing access to an increasing number of business-focused apps in Apple's App Store.

Marketing research experts claim that apps for the iPhone and the iPad tablet now compete with prime-time TV shows in popularity.

As per research firm Flurry Analytics, around nineteen million people spend an average of twenty-two minutes per day on accessing social networks or playing iOS games on the iPhone, iPad and iPod Touch.

In addition, several commercial settings have started adopting tablet computers like that of the Apple iPad for a range of purposes, including presentation sharing, visual tours, social networking and for impressing clients.

However, Research in Motion's BlackBerry is still enjoying majority share in the business smartphone market. According to figures compiled by research firm ComScore, BlackBerry owns more than 50 per cent share of the corporate smart phone market.

Canada-based Research in Motion is making efforts to continue keep a firm grip on its market by making its devices more attractive, and by rolling out a tablet computer, called BlackBerry PlayBook, of its own.
