This semester I have decided to go full digital with my text books and I wanted to know what are some good, hopefully free, PDF readers.

I currently use Foxit but I would like to know if it is the best one or if there is better software out there.

Firefox browser supports pdf now. Sumatra is the one I use when firefox fails.

Adobe Reader is free and that's my main pdf reader.
MS Word if you have it can also read pdf files, but converts them to doc files.
I also make use of PDFill (download.com has it, also free) for editing and for printing online docs as pdfs.
