Why Microsoft ?

In the constant world of IT my partner and I are coming to the very same conclusion when it comes to recommending OS’s for our clients. Why Microsoft? Besides the constant security issues the stabilization of the platform gives me a queezy feeling in my stomach. So here and now I submit why not Novell or Linux for server platform standard. Because it is obvoiuse to me Microsoft is less concerned with quality and more concerned with getting something out the door. Please we would like to here your comments.
