OKay, I'm a complete dummy when it comes to Unix/Linux. I was under that impression that it's just like Windows, but not windows? I'm sure I sound like a moron.

First of all, I hate windows but I'm so very much a pc user. I'm not all that in love with Macs so, Mr.Gates seems like my only option, eventhough I don't liek Microsoft.

I just want to know what Unix/Linux is like? I mean, can I wipe my computer clean of Windows and just use Unix? Help?
