This just in from Apple: "MobileMe ends June 30. Although there are good standards-based ways to make your contacts and calendars available, we will arbitrarily disable those features in OS/X until you upgrade your operating system and, we hope, purchase new hardware from us."
OK, maybe that's not the way Apple put it, but that's the message I hear. In my personal life, Apple is starting to drive me crazy with planned obsolescence. And now that the iPhone is a part of many of our enterprise deployments, Apple's planned obsolescence will start to drive us crazy at work, too.
