I'm not a loyalist to either Apple or Microsoft. I pick and choose what I like. It's no secret that Microsoft's modus operandi is to take Apple's ideas and make it their own. So, in a sense it's no surprise that Windows 7 will have support for multi-touch. The Windows page preview looks exactly like the iPhone's and the taskbar with the iPhone looks like the current Mac OS. The overall look of Windows also looks very much like the Mac.
From what I can see, Microsoft is now pushing. I hope Apple pushes back. HARD.
