Well I know that 06 works with Linux. And you have contradicted yourself about how Linux is user-friendly and supports everything but it won't run anything later than 2006…
I know Linux is free, and I have looked at Linux many times over the years. Software development just isn't there and very well may never be. When I was editing video professionally, lack of any real "professional quality" video editing software along with absolutely no support for the Matrox RTX-100 ruled out Linux for me at that time.
I attempted to put Linux on my Dell studio XPS 435 MT back when I first got it about three years ago, wouldn't support the audio, network or video card (which was an ATI 4850) at that time. I've since upgraded video cards but I'm not going to run out and try to install Linux just to see if it will or will not support my hardware.
There is an old adage "you get what you pay for." I also firmly believe that if you make something free, you destroyed any intrinsic value it might have had. I'm getting up there in years, and it's been my life experience (and this has never failed) nothing I've ever had in my life and I do mean nothing where there is a free version and a version that isn't free, never has a free product equaled the quality of the same type of product that wasn't free.
If you're not using Windows 7, it's really your loss. I've been using computers since basic on the Altair, I've used basic, assembly, OS nine, OS 2, every flavor of UNIX, DOS from 2.1, every version of Windows up to seven, still have a copy Windows 2.1 shrink-wrapped, just about every flavor of Linux, I'm probably forgetting a few different operating systems or languages but you know what? Windows 7 64-bit loads up every time I start the computer, and eight or nine months now it's never locked up or crashed. It always shuts down when I tell it to, and the most important thing, it runs every program I want it to run, and it doesn't complain…
