:.Do you think linux will be the next prominent OS.: No....Linux has been around for quite a long time and as far the General Public-The majority of computers are Windows based by a large margin (97%?) - which is shame since Linux is such great OS (as any X based is) but as far as the consumer market it still has become very popular and has a small segment that do use it. It's doing well in regards embeddded applications (everything has almost become a computer so.) In regards to security in general, it is more secure v Windows but as it gains popularity - you'll see more virus aimed at Linux. No OS is completely secure and since Unix had a backdoor programmed into it and still remains secure..much more so then Windows but as above stated:When the majority of computers run on (In this case Windows) the best target will be that.
