Could your business be paying for a proprietary program when an open source alternative exists? Take a look at our guide as we count down the most popular open source products.
Much of the software suggested in this round-up came from sourceforge.net, known colloquially as the open source "phone book". Alternatively, you might want to look at Wikipedia's Free Software Portal. If you need software, it's well worth a look.
Although this round-up lists a range of the popular open source applications, it's far from exhaustive, listing only a small sample of the vast array of free applications available. If you have your own favourite open source application, please let everyone know in talkback.
