I finally have it in my hands!
As Geoff described it, "its... purple". The cover changed from this to this, much to my surprise. So my companion Web site doesn't reflect the changed cover yet. Oh well. After reading about the Appian Way (the image on the cover), I like the cover more.
I managed to keep it nice and concise (O'Reilly size you might say), and it has a nice scent to it that I think readers will enjoy. Just put your nose between the pages and take a deep breath.
I also found out I am speaking at OSCON this past week, so it has been a pretty good week overall.
