And when you leave the work radius at lunchtime with the cute coworker you're flirting with, you suddenly hear your wife over the in-vehicle bluetooth handsfree.
I wonder how many conditionals you can string together. "Remind me to call my wife before I leave work" is great, but "remind me to call my wife before I leave work at the end of the day, unless she calls me first" would be awesome.
In reality none of this stuff is even remotely useful, because I can't even begin to guess whether or not a given command will be interpreted properly. Natural language is hard, and reminders need to be 100% reliable.
