NVDA (NonVisual Desktop Access) and Kindle for PC 1.19
With the release of Kindle for PC 1.19, it is highly probable that it will soon only be possible to download non-KFX files if you have a pre-PW2 Kindle. This means that if you only have a Kindle newer than a PW1, you will not be able to remove DRM or convert your books to other formats.
Will this affect your ebook buying habits? Do you expect to go to vendors other than Amazon to get your books, and if so, what vendors will you use?
Edit: To be clear, no users are currently in danger of being unable to convert, backup or remove DRM from their Amazon books. Both Kindle for PC versions 1.15 and 1.17 are still available and functional and will download a non-KFX file to your PC. But uncheck the auto-update box if you don't want to update to the latest 1.19 version. In addition, USB transfer still downloads non-KFX files which can be de-DRMed. So don't panic! This thread is purely speculative and there is no immediate threat to you de-DRMing your books.
