I’ve been a big fan of Foxit’s PDF reader for a while. It is a 1.5MB download, and it is blazingly fast to display PDF documents. I must admit, with version 1.3, I did notice some PDF documents (maybe 5%?) were unreadable for various reasons by Foxit. This was frustrating, because I really didn’t want to download Adobe’s 60-ton Acrobat.
Good news – Foxit has a new version 2.0 available for download, and it seems to be solid. I not a good enough PDF tester to know how good it is, but it is the only PDF viewer I have installed, and I haven’t seen any errors yet. If you haven’t tried it, you should, it will change the way you feel about PDF!
