Thanks for the link, Jabby! More karma to you! So far I have only tried Aldiko for reading (but haven't done much reading on the Tab yet), and ezPDF for PDFs (my scanned comics) as Aldiko (the free version) didn't work well in landscape mode but ezPDF does. So Mantano Reader, according to other posts in this subsection, may be good for me as the author says MR is like aldiko+ezPDF. I'll check to see if freewarelovers offers it
Now if I could find an app that would give me tons more time to read...!
