Thanks everyone for sharing your experience. I'll have to look at a couple of these options again.

I went into Kybook 3 to look around and read, thinking I'd likely go ahead and purchase and try to "settle in" to it, since it seems to have most is the features I'm looking for...

However, there was a "gotcha" that I wasn't expecting. I have no problem paying a few dollars for a good app but I don't like subscriptions. I found that while you get most things with the paid version of Kybook 3, of the the features that it's a must have to me, namely syncing across devices, costs $15 a year! And, that's the only feature they said you get beyond that $15 paywall. Everything else is included in the one time payment. The main reason a lot of people use the tanned iOS ecosystem is interoperability between devices. It's generally so slick and smooth. Taking that away and making that the only feature you get for $15 doesn't seem great to me. So that was disappointing. I'll look again at Aunt I'd the other apps. I do have not only Documents by Readdle but their PDF Expert too so I can use that for reading, if I'm willing to use a different app. It runs in my mind though that I ran across an app in the last few days that offered text reflow for PDF files in the iPhone. That would be a pretty cool feature, potentially. I'll have to try to find out which one it was.

Thanks again for all of your input. I'll try Yomu and TiReader again too to see if either seems worth keeping.
