With all due respect to Novell, I'm not sure scavenging in my top competitor's pockets for lunch money is something to crow about. Interoperability is great. Being a vassal to Microsoft is not. (The word is appropriate, Novell - look it up.)
How can Microsoft removing Novell from effective Linux competition possibly be good for the market, or for Novell, long term? I understand that it's a lot of money, and that's great. In fact, I would assume that nearly every penny of Novell's profit in 2007 came from Microsoft's wallet.
But this isn't a recipe for success. Microsoft does not have Linux's best interests at heart. The minute Novell becomes more of a threat to Microsoft than Red Hat is, Novell will be shunted aside. In the meantime, Microsoft is Novell's sugar daddy, making Novell a mere vassal to Microsoft.
