Jason Fried and David Heinemeier Hansson, founders of 37signals, had their new book Rework hit stores today. I heard about this book several months ago and setup an OmniFocus reminder to notify me of its release. I've already sent a sample of the book to my Kindle and will be digging into the text a little later today.
If given a choice between investing in someone who has read REWORK or has an MBA, I'm investing in REWORK every time. A must read for every entrepreneur.Mark Cuban, co-founder HDNet, owner of the Dallas Mavericks

Can't wait to read this one. Well, I will, I mean I'm going to finish my current book (The Checklist Manifesto) first but its next on the list!
Listening to the 37signals podcast about Rework right now. An interesting bunch.
Sam, do you have a link to the podcast episode where they're talking about Rework? I'd love to check it out.
I can't find a link right now but try searching for 37signals in iTunes.
Here's the link to the 37signals podcast http://bit.ly/aIhaZq (iTunes link). The particular episode about Rework - for those interested - is called "All about REWORK."
Clark Valberg just sent it to me on iTunes yesterday; I'm pretty excited to check it out. Currently listening to "Switch" - a very interesting book about behavior modification. After than, 37 Signals all the way.
