Yup, I own it and the old managing actions and projects series also.
GTD fast is a great investment--definitely adds more clarity to the book.
I own the audible version of the book also (wasn't as impressed with it --too condensed)
Would really like to see leveraging focus and vision seminar put to cd format
Ps --we've discussed GTD fast a few times on the board already . Should show up in the archives etc.
