Here is some feedback of the experience of running this s/w on the Acer M900.
Once you've executed the option to associate MobileXpdf with PDF files, then opening a PDF file from File Manager brings it up in MobileXpdf ok. However the print is far too small to be able to read it. It takes about 6 Zoom In operations before it is large enough to read - hence we really need a Zoom to X% list...
