I've clearly lost brain cells as I've gotten older, but I think I've been able to maintain a constant rate of learning new things by reducing the amount of slack and drag in how I work (and read)...I really like the selling point of "As a developer, I value my time at $100/hr and this book will save me 30 min/day...This means I will have an extra $12,500 per year". That's a nice way to think about it, though it probably underestimates the impact of more time in life.
I like the pricing of the video (at least at the launch price)...I almost never learn via video (yes, I'm that old) but for an extra $9 (or +$5 of the regularly-priced book)...that's not at all a bad deal. And I've been trying to make screencasts on workflow and tooling and am always interested in how the pros teach with video.
So, sold.
