Mobile workers are getting left out in the cold as battles between vendors continues. I mentioned a few weeks ago the dispute between Google Voice and Apple over allowing Google Voice into Apple's iPhone store. This week comes news that Microsoft is delivering enhancements to its Office Communicator Mobile, which only runs on Windows Mobile and Nokia Symbian devices. Microsoft also announced new partnership with Nokia. Great, but according to our research, the vast majority of business smartphones are, and will continue to be BlackBerry's, while 38% of companies are adding support for iPhone over the next year. Enterprise mobile planners are increasingly getting stuck in the middle of efforts by mobile providers to own the operating system, the device, and the software. A trend that appears to be accelerating at the expense of innovation.
