I'm looking to buy DRM-free eBook editions of Beginning ASP.NET 4 and Beginning Visual Basic 2010 to read on my Kindle device. However, I also prefer to read eBooks on my PC in PDF format.
I notice that the range of Wrox eBook formats on O'Reilly.com varies from title to title, and include some combination of ePub, Mobi and PDF.
As such, my question is two-fold:
1. Does Wrox/O'Reilly plan on adding missing formats (eg. PDF) for existing/above titles?
2. If I purchase the above titles now, and PDF format is added to O'Reilly.com later - does that become available to me automatically, or does it require a separate purchase?
