If a title is only legally available with DRM, I'll just do without, not pirate.
When the book is available non-DRM, such as from ebooks.com, I've paid a hefty premium over the Kindle DRM price.
Thanks to O'Reilly for being clueful enough to sell non-DRM versions.
If the DRM situation gets even worse, I don't know what I'll do. I'd like the DRM situation to get better, not worse.
