While standing around the water cooler in the IT department, perhaps you debate with a coworker about whether LinkedIn is better than Facebook. Or you argue with an end user about whether they can use their own device on the corporate network or can only use what is provided by the company.
Technology is always evolving, and the nature of these arguments has changed. Just last year, for example, social networking looked like a two-horse race between Facebook and Twitter; now, LinkedIn and Google have come charging back. In data center switches, Brocade and others have muscled their way into the battle between Cisco and Juniper.
Companies have changed their views on whether employees can bring their own devices to work, and this is having a profound impact on IT as a whole. No longer is the iPhone forbidden at work, and no longer is the BlackBerry the only game in town.
