Backpack
by Martin Neumann ~ January 7th, 2007
Backpack is a simple web-based service. You sign up, log in, and use the product over the web through your web browser. You can make to-do lists, jot down notes, share files, upload photos. There’s no software to download and nothing to install.
This popular service is used by many to be more productive with my favorites bits being the To-Do list and the research/collect capabilities. Sharing files across business associates is a breeze. Backpack is just about a must-have for any serious online entrepreneur.
