Not sure how I missed knowing about this book (obviously I'm not as obsessed with your career and goings-on as I should be, Alex
)!
Anyway, I just ordered a copy, and thought the following were interesting:
1. Neither bn.com (Barnes & Noble) nor buy.com appear to have ever heard of it, so you can't order it from either of them! <_< (I usually prefer those websites because Amazon is based here in WA state, so I have to pay sales tax to buy from them...and I'm cheap.)
2. Amazon.com pulls it right up immediately; I didn't even have to go to Amazon.brit or whatever the UK version is (like I did to get your earlier book, The Art of Diving, which I love BTW).
3. Apparently Amazon USA still doesn't keep the book in stock, because their "delivery estimate: April 14, 2008 - May 2, 2008" is 6-8 weeks from now! So if anybody is thinking of getting a copy for a special occasion (e.g., for their own birthday, anniversary, May Day, 4th of July, etc.), they oughtta order it NOW, not wait till the last minute.
4. There isn't a single buyer review of the book on the Amazon listing, so Steve (and others who own it), you ought to take a minute to go enter a review - heck, just cut and paste some of what you posted in this thread! You might help Alex sell a few more copies, enabling him to afford an extra order or two of fish & chips, which he surely needs! 
Anyway, I'm looking forward to getting my copy - it's not often you are virtually guaranteed to get your money's worth when you buy something, but with Alex's work, I'm confident that is the case!
