Well guys, nice question.
Every piece of hardware comes with its supporting software and price of that s/w adds up with the total hardware cost which u pay to the dealer and assumes....

u are getting free software.
We all are so smart (or atleast think) but whenever we go to a branded h/w we simply pay for the s/w too.
Like if u buy a brand new PC you will pay for XP Home Edition.
or if the PC is lil cheaper then they must be using LINUX.
So guys don't think that u never paid for a s/w and u r so smart. Even we pay for on-line security s/w which is provided by our ISP or broad band wala.
