I`m 60% geek.
I make my living in the Information Technology industry.
I dual boot my desktop and laptop machines With Linux and Windows and I`m always comparing the latest Windows and Linux offerings.
Windows invariably ends up as my primary OS because there is no other OS that allows me to do everything so easily.
To get any version of Linux to the same level of Windows do evethingness takes weeks if not months.
Eventually I hit the wall of Linux application incompatibility, and boot back into Windows because I don't feel like loosing another day of my life researching a workaround for something that I could do within a few minutes in Windows.
The thing that I find Ironic, is that I put some of my less than technical friends and family on Linux... their needs are very basic compared to mine, and they have a hard time messing up Linux just by surfing the internet.
Which means allot less free "just call Dieter support" and headaches for me.
In my opinion Windows is easier to customize and in the hands of an expert you can get it to do anything... speedy, secure and stable with far less effort than Linux.
Right now I`m using the latest versions of Open Suse, Ubuntu and Windows 7.
I`m VERY impressed with Windows 7, its Linux fast and it runs all of my applications and hardware out of the box.
I think that the Linux distros are improving at a faster rate than Windows, but in my opinion Linux has still got a long way to go before it can become my primary OS.
