There isnt a conspicacy with linux. Yes, it is best to run servers on it because it is very secure but within the hands of a noob the OS is pretty worthless thats why windows is so mainstream because its more user friendly. Not many people want to take the time to actually learn commands and sub commands to run a system efficiently. They just want to get to something really quick and fast-- This is where security comes in. Windows is very insecure and cannot be ran for a very long time. Im running servers on the computer I use and the first i tested was windows and it failed miserably. A funny thing is windows is scared of linux and its a free open source OS and Microsoft is one of the biggest induistries in all of business.
