Once upon a time, not long ago, there was only one smartphone firm on the lips of any business' IT team when it came to company phones: BlackBerry, the Canadian company formerly known as Research in Motion (RIM).
A lot has changed since then and BlackBerry's fortunes have taken a turn, leaving the door open for rivals to court the enterprise business and forcing it to embrace (or as some may say begrudgingly adopt) Android at the core of its new flagship handset.
The rest of the pack is hot on its heels, if not already overtaking, with Apple, Samsung, Microsoft, HTC and others all vying for a piece of the lucrative business pie.
This is great for any potential business buyer, as you now have a wide choice of mobile smartphones to choose from, allowing you to select the best phones for your company's requirements, regardless of the size.
In no particular order, here are the top smartphones for business use and business users:
Microsoft Lumia 950/950 XL
Getting you ready for Windows 10 Mobile
These two smartphones represent the best-of-breed devices when it comes to Windows 10 Mobile, Microsoft's latest mobile operating system, one which promises, for the first time ever, a seamless user experience, across applications and across displays.
Both devices share similar features like 3GB of RAM, 32GB onboard storage, a 2K display, a 20-megapixel rear camera and a free one-year subscription to Office 365 Personal. Connect either phones to the Microsoft HD-500, a £80 Display Dock, and it transforms into a powerful desktop PC as well, great in an enterprise configuration.
The first BlackBerry handset with the Android sauce
When the Priv launched, it took a lot of analysts by surprised because of radical step involving the OS. BlackBerry had finally decided to embrace Android and re-introduce the keyboard (albeit a slide out one) on a flagship handset. It is, as techradar's John McCann candidly puts it, the mullet of the smartphone world. "It's still business in the front, but now there's a party in the back too. It will divide opinion, but this is the best BlackBerry in years." he added. The device will appeal to those who wants the security halo associated with BlackBerry with the ubiquity of Google's Android. Overall, it remains a stunning piece of kit, and probably one bound to become a classic.
For those who yearn for the golden age of BBOS
There are still BlackBerry fans out there and the Canadian company unveiled the Classic to please them all. An old-school QWERTY keyboard, a familiar operating system and user interface, a design that doesn't age and the enterprise-grade security are all on the feature list of this smartphone.
Sure, Android might well have the upper hand when it comes to market share and the sheer number of applications but BlackBerry provides with yet another attractive alternative when it comes to business smartphones. It runs BlackBerry OS 10 with a square 720x720 pixel touchscreen display, a touchpad and up to 22-hour battery power.
Samsung Galaxy S6/S6 Edge
The best Android smartphone for business yet?
With every iteration of its Galaxy S series, Samsung edges towards the business user. The S6 and the S6 Edge saw the inclusion of Microsoft Office Android applications as well as Samsung's own mobile device management container solution, Knox. The latter provides military-grade, multi-layered mobile security.
Siloed personal and work partitioning containers (Knox Workspace) means that employers can separate work and personal life in a near seamless way. Great for BYOD aficionados. Samsung also wisely scrapped the plastic finish for a more upmarket design that blends glass and metal, one that's particularly appealing in the Galaxy S6 Edge and its curved display.
