I know most people in India, including me, don't give a **** about its illegality and about software piracy so I don't expect you to either.
However, I do want to caution you that Mac OS X is designed only to run on Macs. It does not have the device drivers for any other hardware components apart from the ones which Macs ship with. Even if you do manage to install Mac OS X, which is no easy feat on a non-Mac computer, your experience using it will be fraught with various driver issues and such. It will be crash-prone and slow and there will be a lot of incompatibilities. Basically, it won't be much better than what you are used to with Windows.
So why bother! If you really want to try out a Mac, go to any Apple Authorised Reseller and you can use the Macs on display for as long as you wish to. No one will stare at you and you won't feel unwelcome. Give it a try.
