I too have a older Sony Reader... and love it... LIke *ZTAgirlknits* mines does not have the bells or whistles and no wi-fi..... so far I've never felt left out or a need for any of that.... DH bought mine because I too am vision impaired... and I make that font just as big as I want... There are tons of free books/cooks/ short stories/mag etc out there.... Many librarys do have things in ereader formats ( my small town lib does not) I have purchased 100's of books from ebay and amazon at rock bottom prices.
I have several hundred books waiting on me at any given moment. I love it's size and yet so many books in it.
and yes the battery is awesome... I read for weeks on end before I need to recharge it....
