I have a very old (cheap) Nook and have a tablet which I use to read the books I buy from Amazon.

1. The particular Nook I have doesn't have a full touch screen - very annoying

2. However, the Nook I have (B&W) - the battery lasts FOREVER!

3. I really prefer the ePub format

4. I really prefer the full touch screen of the tablet

5. I like how I can easily share books with family members via Share in Amazon (sister has a Fire)

6. Amazon makes it soooooo easy to buy books (maybe too easy)

I am looking at a way to take the books I buy in the iMobi format and convert to ePub, so that all of my books are in the same format, but I haven't done a lot of research on it.

My sister has the Fire and she can't figure out how to transfer files to/from it - now she isn't a computer expert either, and (in my opinion - being the older sister and a computer programmer) I believe she gives up too easily on anything remotely "technical"...

my 2 cents.
