If you want to purchase these programs you better do so by January 11, 2010. Microsoft just lost a court case for patent infringement and will not be able to sell the product until they have done a workaround. http://www.salon.com/wires/ap/business/2009/12/22/D9COH00O0_us_microsoft_patent
I'm hearing that Microsoft will have a version available on 1-11, that does not contain the code that was the infringement base.
