Hi, nannyto1, and welcome to MR (MobilRead)
Here is the link to the whole forum that neil mentioned.
Which one should I buy?
MR also has a great wiki full of information. There is an introductary page on
E-book devices and
The famous eBook Reader Matrix. Plus, there are pages about
DRM (Digital Rights Management),
ADE (Adobe Digital Editions), and
E-book formats.
Have fun looking around and just ask if you have any questions.
