When Apple initially rolled out its MobileMe service for synchronizing e-mail, contacts and calendars among computing devices, its tagline—"Exchange for the rest of us"—suggested that businesses might find some use for the technology.

The service, however, has little to do with corporate information technology and more to do with redefining Apple's online service as a contender in the cloud computing space. Companies from software maker Microsoft to search giant Google offer productivity applications as services on the Internet—"the cloud" in industry parlance—allowing customers to have access to their data from anywhere.

MobileMe is Apple's first major move in the game. With its .Mac service, the company had collected common Internet activities—such as Web site creation and community groups—into a single offering. Now, the company has a more focused service that competes with other companies' Web applications, but—so far—without the document or spreadsheet components.

"The focus of MobileMe is 'me,' so it's really not targeted at companies," said Michael Gartenberg, vice president and research director with business intelligence firm JupiterResearch. "But if you want calendaring and contact synchronization, it certainly does the job."

Yet while the service may not be adopted by businesses as a way to synchronize data or provide access to e-mail and calendars on the road, employees may take to the service and bring it into the workplace. Already, Apple has focused on making its iPhone mobile device enterprise-friendly. It's likely that workers will follow suit with MobileMe.

The Consumer Feel of MobileMe

Here's how MobileMe works. For an annual subscription fee of $99, or $149 for a family of five, consumers get a polished experience allowing a single user to synchronize calendars, contacts and e-mail between Macs, Windows PCs and iPhones. Subscribers can also save files to online storage, known as an iDisk, and synchronize those files among computers. The service also allows photos to be easily uploaded and shared as well as provides rudimentary editing functions. Finally, the collection of applications can also be accessed from any computer through the Web in a way that mimics Apple's desktop versions of the software.

Setting up the service on the Mac or iPhone is simple, requiring that the user update Mac OS X and Apple's iTunes software, which the company continues to develop into a more general data-synchronization hub. Users of Microsoft Windows will find the process a bit more involved, but the end result is nearly as good.
