The trend here is for new technologies to be made available for the consumer market before they are available to the business market. Businesses are under pressure to use these new technologies. Younger employees simply are not satisfied with using outdated technology. They're either going to figure out ways around the corporate security rules, or change jobs to a trendy company. With cloud computing a lot more employee computing devices are nothing more than dumb terminals with a browser interface; When corporate e-mail is all webmail, corporate documents are all on GoogleDocs, and when all the specialized applications have a web interface, it's easier to allow employees to use any up-to-date browser Senior management may also pressure security out of the way, they may want to get to the company's databases from their brand new iPad. With these pressure from employees and senior management, it is going to be harder and harder to say no.
