Just a little suggestion. Hope it helps for you to choose Linux. ;)

Personally, i am really like Linux, and use it since 1990. :-)
I have set up about 30 servers or more...
Usually i can't use the distro-release kernels, because these usually too old. Additionally i can find bugs on any software and in any kernel version....

Anyway, thanks for your suggestion. ;-)
