Of course I wouldn't it. I think that the comparison has little to do.
Windows it's very different from Linux. MS it's product developed by
an only company and closed souce. I think that the difference from
using some distro with different kernel is far smaller that running
"Vista" apps on Windows 95. Of course I don't expect support in the
sense that someone solve my problems, I'm only was asking
suggestions...
