One thing I noted when I first reviewed photo books back in 2006 was that most vendors were based overseas, resulting in quick printing times but a protracted and expensive delivery process. This was true of Apple (both times), MyPublisher and Printing-1. The one company that I tried that were UK based, PhotoBox, was let down by its browser-based interface that was less flexible that the native applications of the other vendors.
I was therefore quite intrigued when YoPhoto asked me to take a look at their brand of photo book as they seemed to offer the best of both worlds.
