Personally, I pick the best eReader for the majority of my reading sources. I'm partial to the eInk screen and the resulting extended time between recharges. My local library doesn't have eBook lending (yet) and will no doubt go to ePub. But I still have options to deal with it. pBook checkout is one. The other is that with the appropriate FREE computer apps, you can buy and read anything from Amazon, B&N, Borders, BAM or your library on your laptop or Notebook, or Netbook, or Tablet or even your little smart phone (if you can deal with a tiny screen and shiny surface reflections).
