This is one question which haunts the minds of consumers and developers alike. Businessmen are the people who need hi-fi smartphones to stay in touch with their business on the go. It is they who use all the features that a smartphone offers, such as document viewers, PDF scanners, open office suites, etc. Therefore, that is a customer segment these smartphone manufacturers and operating system developers should keep in mind while creating phones and interfaces for the same. Speed, agility, capacity (memory) and a number of other features of high end mobile phones are to be taken into consideration while awarding the best phone for a businessman. In this article we consider a number of factors such as user interface, availability of apps, etc. and select winners in each category.
Till recently, the user interface was one of the most ignored criteria by mobile platform developers and manufacturers alike but then they seemed to realize that looks and usability matter. Therefore, since not far behind from now, people have been according top priority to the interface. The forerunner in this regard, i.e. creating a smart phone with an unbeatable user interface was Apple. Before you call me biased or just another Apple fan, show me a phone that was released before the first version of the iPhone and has a better UI. I bet you can’t because such a good mobile simply does not exist. Right from the launch of Apple’s strikingly successful iPhone featuring an interactive iOS, mobile phone manufacturers across the world have realized the need for a better UI and thus simple yet elegant phones with easy-to-use interfaces have been rolling on the market. Therefore, the indubitable winner of the category is the iPhone.
However hard an Apple fan I might be, there is something I hate about it and that is exactly the thing I like about it-the exclusivity. I like it because it keeps you away from the rest, or in other words, you stand a class apart, but the same exclusivity puts you in a position with limited choices, or rather no choices. If you want the iOS, you should buy an iPhone or a BlackBerry for a BlackBerry OS, for that sake. There is simply no other go. But that is not the case with my latest favorite, the Android platform. With hundreds, or probably thousands by the time you read this review, of phone being run on Android OS, the choices of hardware and branding proffered to an user are drop-dead gorgeous and mind-blowing. Of course, it leaves you with some confusions on which phone to choose, that runs on Android, but the choice is all we are looking for and nothing can beat Android in that regard.
Another factor that needs to be considered while comparing the three giant OS’s of mobiles is the availability. I feel BlackBerry outperforms the other two in this regard as all its mobiles are available across the world within a short span of its release in its primary market. Apple’s hyper-concentration in the US has devoid it of its rightful place and Android’s delay in hardware compatibility between various regions across the globe has pushed it back from being number 1.
Blackberry, as an OS, is pretty good for businessmen but there is something unexplainably lacking in this OS. It is probably the fact that not many apps support this exclusive OS, which is even more exclusive than the iOS, contrary to the ever-supported Android.
Therefore, though iOS and BlackBerry prove to be extremely functional and fancy when it comes to mobile technology, our choice of best OS for businessmen goes for Android as it is more open, less exclusive, easily available and not picky about its choice of brands.

I would like to add that although iOS devices are a class apart but Android has allowed more and more users to experience a ‘Smartphone’. Every one can now get a Smartphone for their budget and their choice of features!
Android has too personified the Blackberry Playbook. I am looking out for it this month.
here is a post that compliments your article. The author well explains why Blackberry Playbook will be a success with the Android SDK.
