I read a lot of PDF files, on both my iPad and my Windows PC. I like the PDF file concept a lot, but I am constantly amazed at how large and bloated the readers have become. The latest version of Adobe's reader is 48 MB, and pretty resource-hungry once installed.
So imagine my delight when I recently discovered a PDF reader called Sumatra. It's available for Windows, and it's free. It's only 2.5 MB to download, it's lightning fast to start up, and it's portable so there's nothing to install. Just double-click the single .EXE file once you've unzipped the download, and away you go.
It'll even read .djvu files (created by Deja Vu, which is a format that competes with PDF), and is malware-free according to Virus Total.
