I saw this and thought I would publish this to show that businesses will always put differences behind them if they think there is a buck to be made:

Sun to Install Windows Server on Its Hardware

Sun Microsystems will start selling its lineup of 64-bit, x86-based servers preinstalled with the Windows Server operating system within 90 days.

and

Microsoft/Novell Open Windows/Linux Interop Lab

The initial focus will be around three projects involving virtualization, management, and identity federation.

This just proves that all firms are commercial!  Don't believe the religious hype!  Of course, competition will still be just as fierce.
