According to TGDaily, US District Court Judge Marsha Pechman released figures from the class-action lawsuit. An expert witness calculated that it would cost between $3.92 billion up to $8.5 billion to upgrade affected machines so that they can run a premium version of Vista. Wow.

A University of Washington economist, and an expert witness for the plaintiffs has calculated that it would cost anywhere from $3.92 billion to $8.52 billion to upgrade all of the PCs that were sold as Vista Capable so that they would be able to run the premium versions of Windows Vista. This number was computed by utilizing data provided by Microsoft, and arrives at how many "Vista upgradeable" PCs had been sold in the United States between April 2006 (when the Vista Capable Campaign began) through to January 2007 (when Vista hit the market and the marketing campaign ended). It was deemed that 13.75 million notebooks and 5.65 million desktop PCs had been classified "Vista Capable" when they were not actually able to meet the harsher "Premium Ready" requirements. Basically, Microsoft certification branded "Vista Capable PCs" as such without stressing to consumers that the PCs were designed only to run at the barest minimum of Vista Basic - which is the lowest level of the many products of Vista. Unfortunately, some of these PCs weren't capable of running more powerful versions, or were not able to run all of the program features in other versions.

The Vista Home Basic lawsuit alleges that Microsoft's Vista Capable program would inflate the prices of PCs that were only capable of running that edition, thus enticing users to purchase machines that would not be able to upgrade to a better version of Vista at a later date. Individuals and consumers involved in the lawsuit feel that they were cheated, and not given the "real Vista" because it doesn't have the Aero glass user interface.
