OpenOffice: Worth $21 Million Per Day, If It Were Microsoft Office
rbowen of SourceForge writes with an interesting way to look at the value of certain free software options: "Apache OpenOffice 3.4.1 has averaged 138,928 downloads per day. That is an average value to the public of $21 million per day, as calculated by savings over buying the competing product. Or $7.61 billion (7.61 thousand million) per year." (That works out to about $150 per copy of MS Office. There are some holes in the argument, but it holds true for everyone who but for a free office suite would have paid that much for Microsoft's. The numbers are even bigger if you toss in LibreOffice, too.)
The summary also notes this is savings to the end user. If I don't need all the features found in MS Office I shouldn't need to buy it. If I get what I need and pay $0 I've saved $150.
That's the whole point of the summary. Some segment of the public are getting what they need to get their "office productivity" tasks done for less cost.
