Yeah it seems that DOS is obsolete these day but naah, not really, let ur windows crash and then u will realise what DOS means . And believe me DOS is pretty stable OS unlike windows which no doubt gives the user a pretty simple interface to work their way through. Comman man needs a simple interface to work with and that is what Windows offers ( very good) but arent people shifting to Linux and realising the power the linux over windows, yeah they are and soon linux is gonna really bother windows in a serious way. Linux only has the problem tat is doesn thave drivers to be able to do all the net stuff but people are working on it and the open source code makes it very flexible and really helpful. WIndows is not the end of the world, Linux may be!!
