I like how there are so many different ways (formats) to buy, it's easy to buy and it's clear what the book is about. Clearly he is following his own advice.
There is probably a lot more room for improvement. Anyone wanting the sample before buying may be quickly turned off. It's a 60MB zip file because the audio is bundled in. This easily deters anyone on their iPhone/iPad.
Not just iPhone/iPad - my broadband's not so very fast when the kids are watching something on NetFlix, and it's dismaying to have that large a file to wait for.
(I bought the book anyway - you should probably give Daniel a kickback, actually.)
