In Wired:  A discussion of the recording of your secrets in the Siri concierge system.  And questioning how long these communications are being held.   What are our expectations?  It might well be that like the typical conversation, you expect it to be immediately deleted.  But the reality may be very different.  Not much different than many of the mail systems, which do store your mail, and you expect it to be available later.
