yes I got it for Christmas, downloaded most of my devotional reading, bible etc. which is a huge help. Not for serious bible study however, too hard to search and find things. Be very picky about what you download and make sure it has been formatted for kindle so their is a searchable table of contents and index, and that the translation of a classical spiritual work is the one you want (I prefer more modern to the Victorian or earlier language). be especially suspicious of free or 99 cent downloads.
same rules as shopping for regular books on Amazon, first shop at a real store and make sure of the edition, author, cover etc. details, so when you get to Amazon you are getting the one you want.
Ignatius press can take you through the steps to purchase and download most of their titles directly from them. Hope other Catholic publishers follow their lead. Which I could get LOTH but not yet.
