AppleBerry, GoogleBerry, which will blink first It's only a matter of time but I bet google buys BB. The Chinese company Lenovo wants it but there's no way the gov't will let that happen because of the security risk (the Chinese gov't will hack the code and no more secure mail).
Google's Android is ok but it's got major security flaws.
Apple's iphone is ok too but not for business. https://seekingalpha.com/article/1256301-it-s-time-for-apple-to-buy-blackberry
Microsoft's winPhone is ok too but has a lot of room for improvement.
All three of these behemoths are flush wil cash and buying BB will be a major shortcut for their R&D not to mention acquiring all of BB's customers, 79,000,000 and all the new ones it's converting from the mentioned companies who are bleeding clients to BB.
So, I bet it's only a matter of time before one of them blinks. I bet it's going to be Microsoft or Google. It just makes good business sense.
