The inability of importing my own epubs and mobi books forces me to live in dual worlds (Logos & Kindle). I also have to remember...was that book one I have in kindle or is it in the Logos world?
I don't like the Kindle reader. I think the Logos experience is far superior. I just purchased an epub book today from a reputable ministry, I really wanted to read the book and search it for future blog posts and possible sermons...the title wasn't available through Logos.
I will probably spend $1,000s in resources from logos over the next few years or so and I am not trying to stab logos in the back. It's frustrating if Logos thinks the personal resources is not a viable area. There's a reason why spotify and itunes let you import your own music. 2 reasons. 1.) They search your stuff and then they know what you like. They then sell you much more of what you like because they've seen all your personal collection. It ends up exponentially increasing sales. 2.) They know you will grow accustomed to being in a certain ecosystem. If you spend hours reading your own personal collection of hundreds of books in the Logos ecosystem you'll stay in that ecosystem and convenience will prevail and you will buy more and more over time from their ecosystem.
Anyway, my purpose isn't to rant. As someone who has worked in ministry I simply want to share my experience and then say as a user I think Logos will make more money from me in the long-term if they let me import and even store in the cloud my personal epub books.
Digital Right concerns aren't a viable long-term concern since all you need to do is have the person agree to terms/conditions when they are uploading letting you know they have legally obtained the ebooks.
