Since we will soon be able to use our highlighting on the iPad, I think this makes sense. I noticed that Kay Arthur uses and endorses Logos Bible Software. It would be great to get both of her series on Logos (with mobile use). Her shorter guides are on Kindle it would be great to get those along with the Precept Upon Precept. If they are available as ebooks, and their author uses the software, it would make sense to have them in Logos or Vyrso.
Please consider this, until then it's the 4 finger swipe between Logos and Kindle when I do the study.
