Windows Vista

Have any of you heard of Windows Vista? It's a new desktop like Windows XP or '98. I really don't know much about it but some are saying it's trying to copy off of Mac OS X. Is that true? I've always been a Windows fan, and I think I always will be (even though I do enjoy Mac's iPod). I'm always wanting the new innovations about technology. Especially if it looks pretty =] Haha. I Windows Vista looks nice, but so far all I have heard is that it hold Windows Movie Maker and the other Windows components. They have those in the XP. If you own a Windows Vista or know more than I do about it, please do share information. I'm starting to get really interested. I tried to look up videos on YouTube about it but it only showed ones with a competition towards the Mac OS X. I was hoping to find videos like the one for the iPhone, which i have an earlier post about.
