Thus far, Logos has been best suited for reference books and commentaries. The number of people who enjoy sitting in front of a computer to read a long book are few and far between. That's why the Kindle has taken off; people don't like to be tethered to their computer to read off the screen for long periods of time.
But now that Logos is going mobile on the iPhone (and it sounds like other mobile devices in the future) and computers are becoming more portable, I think we could find a number of people utilizing Logos to simply read.
This opens the market up even wider for Logos to take advantage of the customers making the digital transition. Why would you opt to use the Kindle reader for iPhone when you could use Logos that has more powerful search tools, offers verse lookup, and library integration? The only reason I could think of is that many books (especially current releases) simply aren't available in Logos, but they are for Kindle.
So I really hope Logos starts agressively going after reading-type books. The success of the John Piper library should be a good indication of the market for this, that is only going to quickly increase with the portable revolution.
Let me recommend that Logos start by going after (my preference is in that order)
