Stunned is the word for it. There I was getting to know my new Samsung Galaxy Tab 2, a tablet running Android 4.0 (Ice Cream Sandwich). I configured the built-in Exchange ActiveSync client (using certificate-based authentication, but that's a discussion for another day) and was browsing around the interface when I spotted an oddly familiar-looking icon. "Hmmm," I said, "I wonder what that button does."
