A few months back, while driving the 101 (haha, remember that fun?!) I listened to the unabridged audio version of Welch's Straight From the Gut, about his long career at GE. I pretty much came to the conclusion that he earned his reputation as a great CEO.
Glad to see he's not just playing golf in his retirement. This new book (to be released in April) looks good—if you're into that sort of thing. (The Amazon page has "A Letter from Jack.")
