Does the device share matter though?
Maybe not. Apple will sell a ton of devices and capture the healthiest profit margin in the industry. But revenue on the back end won't be a factor. Samsung will make Android more popular in the enterprise and could capture some services and software revenue. Microsoft won't be a huge device player, but will have its enterprise mobility suite coupled with Office 365 and a lot of back-end tools to sell. BlackBerry will still be found in the enterprise, but the future rests on its BlackBerry Enterprise Server 12 launching in November.
What vendor would you rather be? The Gartner graphic highlights how the actual device is just a part of the enterprise mix. The real money and enterprise mindshare will be made on software and services. In the final analysis, every device, sensor and thing will simply be an endpoint to manage, secure and serve up data.
