Karina, from my about 3000 PDF files stored into a 16 GB SDCARD in my Acer Iconia TAB A500 with Honeycomb 3.0.1, your program haven't been able to recognize any PDF via automatic search.
It is not capable to open any of my PDFs. I've tried some of purchased Scientific American ones (NO DRM), one of about 250 MB scanned by myself and other net available PDF and none had been able to open.
THat with the last available version in the market.
Both RepliGo and ezPDF reader had opened then succesfully. Tried PDF are:
Ensayo sobre ciencia ficción: http://e-archivo.uc3m.es/bitstream/1...ATURA_2008.pdf
Some of Scientific American
Other thing I hate of ebook readers for 10" devices is lack of two/three column mode, mostly in landscape. If you try to read one book in that orientation you will see the insane it is. And only CoolReader implements a two column mode (but it has other problems as lack of formatting)...
