I was just reading FUMI's weblog and saw this new MOOK. I think it was not mentioned here before. Somehow I was thinking lately that if a new mook has to come out, it has to be now (or better a few months ago, when the GXW-56 was not released yet).
I'm not sure if it is an interesting Mook. I have quite a lot, but from the newer generation the 2006 version (G-Shock Official Book) was the best. I haven't bought the 2009 version as it was more of the same. I like the cover of this one though.
