Here is a link to a website I download Sunday School lessons from. Near the top you will find the download for the PPT file and a PDF version.
Thanks for those files. They do show the current limitations/opportunities in the available Android software, if nothing else. RepliGo Reader does a fair job with the PDF when allowed to go through its precaching. Surprisingly, the best app at handling this PDF was Amazon Kindle. Of all the office suites that are installed on my tablet, none were able to show the transitions in the PPT. There could be a decent market for someone who builds a viewer that respects PPT transitions.
The PDF readers I tested were: Adobe Reader, Amazon Kindle, ezPDF Reader, Kingsoft Office, PDF to Go, Perfect Viewer, Polaris Office, Aldiko Reader, RepliGo Reader, Smart Office 2.
The office suites I have are: Kingsoft Office, Polaris Office, Documents to Go, Smart Office 2. I also have Google Docs and QuickOffice on another tablet, but did not test those.
I have to mention though that those two files are incredibly unoptimized. There are two layers of graphics just to make that blue background, and then each picture is at least half a meg in size. I tested converting some of the graphics and found that I could reduce their footprints to at least 1/6th of their originals without losing any perceivable quality. The reason the PDF readers have a hard time with the file is because each page is about 1MB or more to load. Even my laptop has to get off power-saving mode to display the PPT slideshow. However, the Kindle app, which handles the file without sweating, shows that it is still doable.
