Well, I'm more than pleased to make my first post on this Forum about how grand my BB Playbook is for ereading!!!!
The Sony 6 inch e reader is just too small by an inch, lol.
I use Book Reader as my reading app and love the Sepia colour background .... I couldn't ever get a Sony background colour that suited.
Although, I do miss the numerous Sony dictionaries that were part of the Ereader.
In fact I regard my PB as essential to my daily life, and where I go it goes, lol!
