Now the New York Stock Exchange can be added to the list of stock exchanges moving to linux. I'd say you can bank money on the security, stability, etc. of linux...;-) New Zealand changed years ago, and was quite pleased with the vast increase in performance, etc.! And the Chicago Mercantile Exchange moved to linux years ago. :-) And now Tokyo (world's second largest) exchange is moving to linux. It would seem that those who claim linux 'isn't secure, stable', etc. really don't know what they are talking about, apparently ;-)
