Foxit Reader is the latest generation of Foxit Software's lightweight and speedy PDF reader. This Mac and Linux version is not as a fully functional as the Windows build - there's no PDF creation tools, for example, but performance is great, with the program loading documents much faster than Adobe Reader.

There are some limited markup tools - including a highlighter, polygon and cloud-shaped tools, and you can type text directly on to the document too. Recent new features include the ability to take snapshot images of PDFs, plus change the background colour and document text to aid readability.

And document collaboration features allow you to save your PDF files online and work on them with others, via almost any computer with a web browser. This is a commercial service, but a generous 3 month trial period means you've plenty of time to try it out. Check the site for more.
