It is difficult to understate how good Patrick was.
BoS has some of the best speakers in the business. Some you will have heard of - Seth Godin, Joel Spolsky, Geoffrey Moore - some you won't have heard from even if you have heard of them - Peldi at Balsamiq for example. http://businessofsoftware.org/prevyear.aspx
Patrick only had 7 minutes 30 seconds but he rocked the house. He will be back this year we hope.
