Hi everyone,
First of all I thank you all for all your suggestions. Frankly, dint expect so many of you would reply so quickly. :-). This community is amazing.
I am sorry for not mentioning that I already use linux though havent learnt enough for system administration. I use FC 6 and a couple of live cds inclu. Ubuntu. Now I want to change it in my profession too. But I do not know what is required to be a linux professional.
I do not like microsoft for its "way of working". They take away my freedom, my right to knowledge. I can always ignore microsoft. That is what I am trying to do. I prefer to put my efforts in learning and contributing to linux and wish to quit windows completely.
I am not doing this because others do. I have been observing/reading a lot before I made a decision.
I hope I have not raised a wrong question at a wrong place.
Thank you all again.
Regards, Raj
