Hi Geoff-
Congratulations!
I'm sure it's as helpful and well-written as your other books!
I wonder if you've talked with your publisher about offering it in Kindle or another downloadable e-book format (MobiPocket, etc.)? I've put the .pdf version of ReaMix and your User Guide on my Kindle already so I can carry them with me wherever I go. Kindles still aren't available outside the US, AFAIK, and maybe the fact that they're not offering it as a .pdf answers my question, but as much as I like hard copies, it's also very handy to have a whole library in a portable package!
