Thank you all so much. I've really learned a lot.
At the present time, I'm just going to use the app "Stanza" (which is free) for my iPhone.
After I do more on hands research, I'll then see what type of reading device will be best for me. I believe the key is to see if this app will do the trick for me or if I think purchasing a device will be necessary.
Again, Thanks for all the replys and I'll keep reading....
