Last Sunday's episode of Ask the Tech Guys (#2006) includes an interesting discussion about the fact that most modern mobile calendars have some sort of cloud component. In particular, Windows users have to use cloud-enabled Outlook to sync with the iPhone calendar. The long-gone, long-lamented Palm Pilot arrangement came up. It predates the cloud and the sync between the Palm Desktop and Palm OS never shared your data with data sellers or brokers. The hosts couldn't name a modern equivalent. (Although, if you have a Mac paired with that iPhone, it's cloud-free calendaring, correct? Anyway, check it out starting at the 1:22:51 time stamp.
