Has BlackBerry finally reached the point of no return?

Last week, news spilled out that the company previously known as RIM is up for sale. Meanwhile, IDC reported recently that BlackBerry sales are down 12% since last year, while the new line of BlackBerry 10 smartphones has fallen flat.

But for large companies this popular platform has a lingering presence. Many companies still use BlackBerry Enterprise Server. In fact, according to BlackBerry, 90% of all Fortune 500 companies are still BES customers. This includes a wide array of industries, from Vivent (a home security company) to the US National Weather Service to the University of Pittsburgh Medical Center (UPMC), as well as one million US government and defence customers.

Since the launch of BES10 in January, there have been more 19,000 installs worldwide, and 60% of Fortune 500 companies have tested the mobility management product. In June, the company parlayed this widespread adoption: BES10 now works with Android and iOS devices.

At the same time, there's something in the air. Market share has shifted to the iPhone and Android, the most innovative apps always seem to debut on the iPhone and the security landscape has changed. Even US government agencies, including Immigration & Customs Enforcement and the National Transportation Safety Board, are dropping the BlackBerry for the iPhone.

For anyone in charge of mobile infrastructure, there are several reasons to consider finally ditching BlackBerry for good.

1. BYOD makes BlackBerry phones redundant

Experts say we are now in the age of bring your own device (BYOD), even if some companies have failed to embrace the concept. Gavin Kim, the vice president of NQ Mobile, a security company, says the shift in business occurred a few years ago. At one time, most business users had a BlackBerry. Now that number is down to around 10%, he says, compared to the roughly 50% of business users who now have an iPhone.

BES10 added support for other phones too late, Kim suggests. Also, competition from similar asset management and security platforms, such as the Samsung KNOX, make it harder to justify sticking with BlackBerry smartphones.

2. So does mobile device management

MDM firms are also crying foul. AirWatch recently announced that Merck, the pharmaceutical based in Germany, had decided to ditch the BlackBerry in favour of Android and iOS models. The move was meant to increase productivity. Merck even has an internal enterprise application store for Android and iOS apps. Leading MDM companies are like the overlords of mobile infrastructure: When they start losing interest in a platform, large companies usually take notice and follow suit.

3. Analysts bullish about BlackBerry's future

Business analysts have downplayed the importance of BlackBerry devices for the past few years. Roger Kay, an analyst with Endpoint Technologies, says the prospects look dim. While there are still BES users in every sector, the defections have started.

"They really have nowhere to go," he says. "The core value propositions of security and keyboard input has been negated by the other platforms."

4. Innovative app developers eschew BlackBerry

You can still find basic business apps for BlackBerry; some, including Evernote, are even baked into the operating system. There are plenty of consumer apps for BlackBerry 10, too. But few innovative mobile app developers have even bothered with BlackBerry. Companies such as Zensorium, which makes a sensor for the iPhone, and Cue, whose eponymous app reads your email to help you manage your schedule, don't make a BlackBerry app because they know the market share has slipped. For business users, this means falling behind the latest trends.

5. Security innovations erode BlackBerry's advantage

Security isn't just the purview of large enterprise-grade providers such as Good Technology any more. The landscape has changed to include on-device protections such as face recognition (which is admittedly flawed) and complex passcodes.

There are now hundreds of choices when it comes to protecting devices. Apps such as Cobra Tag can help you find a lost phone. You can enable full hardware encryption on an Android device before the OS even boots. Finally, Divide and other apps work well for separating work and personal files on iOS devices.
