Well friends I have started using it from last year. Initially I dont like it because we all love window and only we are only familiar with it but as I have started learning it, I became understand the various advantages of it over windows like first of all its a freeware OS so you will not have to pay a single amount for it. Since its a freeware so if you find any bug in it you can directly review it on redhat community. Its installation is little bit tricky, i.e. it depends on your need if you want a Graphical User Interface(GUI) then you can install a gui interface or if you love command line interface then you can install it also.This OS is mostly use in big government Organizations because of its security. You can also learn many networking features by using command line method.
