FORTUNE -- As a long-time Apple (AAPL) user who doesn't spend much time worrying about viruses, trojans and other malware, I've never had a lot of confidence in the reports issued periodically by computer security companies. They always seemed to be in the protection racket, trying to scare users into buying their anti-viral software.
But a pair of recent reports got me thinking.
The first, from McAfee -- now an Intel (INTC) company -- shows an pretty astonishing rise in malware designed to attack mobile devices, from 792 samples in 2011 to 36,699 in 2012.
The second, tangentially related report comes from Citrix Systems (CTXS), which estimates the adoption rate of mobile platforms in business by tracking their enrollment in cloud services.
Given what McAfee has discovered about mobile malware, it's perhaps not surprising that some enterprises might think twice about letting their employees conduct business in the cloud with Android devices. According to Citrix, 58% of enterprises worldwide were deploying Apple mobile devices in Q4 2012, up 2 percentage points from the previous quarter. Android, at 35%, lost 2 points. Microsoft (MSFT) Windows mobile was flat at 7%.
In North America and Asia the preference for iOS was even stronger: 62% and 75%, respectively.
In Europe, the Middle East and Africa, by contrast, iOS penetration dropped (to 43% from 56%) and Android increased 11 points to 36%.
But what gave me pause was the Citrix chart (below) that showed mobile platform adoption rates by vertical industry. I can see why the user-friendly iOS platform might be preferred in environments in which mobile users engage customers one-on-one, such retail, restaurants and real estate.
But is it really a good idea to be issuing malware-friendly Android devices to field workers in utilities, healthcare and communication services? Citrix was asking the same thing. See Enterprise Mobility Cloud Report Q4 2012.
If Apple's tablet is so great for business, what's holding up the big deployments?
Medtronic bought 4,500 iPads for its sales and marketing teams. Boston Scientific bought 2,000. SAP bought 1,000.
Okay. But where are the rest of the four- and five-figure deployments?
According to Apple (AAPL) COO Tim Cook, 65% of Fortune 500 companies are either testing or deploying iPads. But from the reports we've seen so far -- including the seven MOREPhilip Elmer-DeWitt - Dec 9, 2010 10:23 AM ET
Tech titans are battling to pay big bucks for once bland computing firms. Two questions: Are they worth it? And who's next?
When tech titans HP (HPQ) and Dell (DELL) became entangled in a furious back-and-forth bidding war over 3PAR (PAR), they unwittingly introduced much of the public to a decidedly-unsexy area of tech that is becoming indispensable in our increasingly smartphone'd, tabletized, app-driven world : cloud computing.
In fact, HP's $2.4 billion acquisition MOREJP Mangalindan, Writer - Sep 20, 2010 3:00 AM ET
The clip pasted below may excite or horrify you, depending on your point of view.
It's a demo of a program in development at Citrix Systems (CTXS) that lets you access apps on a computer running Microsoft (MSFT) Windows from an Apple (AAPL) iPhone.
