I use my Sylvania tab to read my PDF's from school. The reader I really like is in the SAM market place ( i know, many people talk crap about it, but its not a bad spot for some freeware). Just search for PDF, download the first program that comes up. Its simple, remembers where you were in your pdf and has a goto page button. The tab is kinda slow loading my PDF's but I suspect its because the PDF's I am using are highly compressed. Adobe reader will display the pdfs, but it dies on me after three pages of reading... Droidreader sux completely and have yet to find a PDF that will work with it.
