Hi Jay and welcome to MR.
To help you with the choice of reader check out the forum '
which one should I buy' which also has a
comparison matrix in the wiki.
After that visit the various subforums for more info. And please feel free to ask any questions to help you decide which reader to get.
Also check out the
eBook library from MR. Sooooo many free books, lovingly formatted by MR members. That'll keep you reading for a while.
