If you think about it, there definitely *is* a difference between Windows and Linux users and what some have perceived as a "culture":

1) Windows users come in two distinct classifications: Average User/Officeworker and Home User/Enthusiast. Their skillset may vary slightly, but those users who are more savvy with Windows usually have no problem with configuring their own hardware firewall, installing AV software and keeping-up on new AV sig-files along with keeping current on the latest patches. The other side of the fence is the casual user who still thinks of "Polio" or AIDS/HIV when they hear the word "Virus". They have no or little understanding of *how* their computer does what it does, and really don't want to know - all they care about is being able to is getting and sending their email, visiting their favorite websites and downloading pictures, etc. It never enters their mind that without proper protection, their systems are wide-open to attack from a variety of means and directions the moment that they connect to the Internet...and even more-so when they are connected using a broadband connection

2) *nix users are usually comfortable playing with chrontab, know what to expect when they type "ps - a" and understand the importance of running fsck once a week. The Hobbyists know most of the in's and out's of their OS, they are absolutely comfortable with tweaking their OS, playing with, patching and compiling a new kernel. Most know how to take care of troublesome bugs and security holes, and some even feel comfortable playing with Gentoo (grin).

The differentiation between the two "camps" - as it were - is that the *nix users & hobbyists have a much different angle on things than the Windows user. More on this later...
