I let Andrew know about the comments about the defective Kindle version of BDA2 and he wrote to his editor at Chapman and Hall, Rob Calver, who wrote back with this info:

I can guarantee that the Kindle version of the third edition will be a substantial improvement.

We publish all of our mathematics and statistics books through Kindle now as Print Replica. This means that we send the printer pdf to Amazon and they convert into their Print Replica format, which is essentially just a pdf viewer. We have not experienced very many issues at all with this setup.

Unfortunately, there was a period before Amazon launched Print Replica when they converted math/stat books into their Kindle format, and converted them very badly in some cases. Equations were held as images, making them very difficult to read. It appears this was the case with Andrew’s second edition, judging by some of the comments.

The third edition [of BDA] will be available through Kindle with a short delay (for Amazon’s conversion) after the print publication. It will also be available through Vital Source and a couple of other e-book suppliers with full DRM.
