No problem with the software, but I find reading an e-book on my phone to be kind of a pain. I can read it OK, but you just don't see much at a time. I'm scrolling about as fast as I'm reading.
It's sort of like watching movies on your phone, another thing that I do not do. I could probably drive in a nail with a screwdriver too, but it's a lot more satisfying when you use the right tool.
