Well, it does say work online or off.  Phoning home is an issue with a lot of programs, including some older versions of Poser. (Remember connecting to Content Paradise at start-up?) Online backup can be a lifesaver, such as when someone breaks into your house and steals everything, including CD's/DVD's and backup devices. Happened to a Bryce mod just last week. Same thing in a flood or fire.

That being said, I'm not crazy about any more contact with Adobe than absolutely necessary.
