Linux at the Bank?

Click on the title above to read a case study about how Redhat is being deployed at the Central Bank of India, a bank with over 3000 branches all over India.Over 1100 branches have already been brought online. The Central Bank of India found a total savings of $1 million over two years in licenses, training and maintenance. Over $500,000 a year in savings...can anyone really argue why NOT to use Linux anymore?I should get our IT infrastructure folks to read this, especially after the fact that most of them were running around installing patches on those pesky Windoze machines after a Sasser worm attack...
