I have never purchased any linux OS before, have seen how they work and how the GUI looks, but never worked on one constantly so I always wondered this question, but I understand that their can be bias when you have people that have their favorites, which I hope people will try to eliminate out there answers. I have heard sys admins complain sometimes about how bad Windows is as an OS. I can understand why they would say that about Vista dealing with the issues I run into with it sometimes myself, but compared to a good OS like XP I don't know how. For example I heard that you can leave a linux machine on for years without it crashing, but can't for a Windows.
A friend asked me the other day which computer should she purchase since I a computer person and she's not? She wanted an Apple, but since I have only heard things about how smooth they run; I don't know for sure as apple commercial says "how a mac is better than a pc." So I could only tell her things that were opinions instead of facts. I understand Mac is not linux, but it is unix-like, so I assumed it shares the same advantages that people say Windows doesn't have, so that kind of makes two questions.
I have found this thread Microsoft Windows OS Usage that gives reasons but not actual facts, and also goes in detail of certain OSes, but my questions is for linux as a whole ex:( RedHat, Suse, etc..)
P.S. I'm not speaking in security, because I understand how Windows is more of a target since its more widely used.
Edit- For a basic home or college computer that has the necessary uses for a person that's not a developer. Which is more reliable?
Edit2 I guess people are not really getting the question here, which is when it comes to home personal use, lets say a family computer, that has to be available for all uses, Is a linux OS would be something to recommend and why? reason being in my own case is in Vista the window explorer always gives me issues,
