Trapani, Gina (9 August 2007). "Open PDF's in a flash with Sumatra". Lifehacker. Retrieved 21 February 2008. The Sumatra PDF Viewer is a tiny open source portable reader that opens PDF's in the blink of an eye. Bloat and startup time is a major drawback to Adobe Reader, so we fled to the faster arms of Foxit Reader long ago. However, at 850KB, Sumatra is way slimmer than FoxIt.
