Whats the equivalent of Windows Vista in Linux?

I am 100% sure that open source community will have an operating system that can match up vista, just take some time and wait, the open source community is growing very fast.. microsoft must be very aware of them, so they make the best they can on vista..

Woow WIndows Vista.. what a hot subject i can say. I have talked a lot in my area with many of my friends and all of them had only positive thoughts about it. I can say that i was blow off by this new windows system. Some things certainly lack to it but this new look which Microsoft has incorporated in it certainly do the money you would give for it. I have waited this new system for 2 weeks and here i am using it. It was pretty hard for me to buy it because in my area it can't be found. So i had to ask a friend from another part of my country to order me. I am so happy using it and all i have are only words of gratitdue. I post here a short description about VISTA. Windows Vista contains hundreds of new features; some of the most significant include an updated graphical user interface (GUI) and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and completely redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network using peer-to-peer technology, making it easier to share files and digital media between computers and devices. For developers, Vista includes version 3.0 of the .NET Framework out of the box. The .Net Framework makes it significantly easier for developers to write high-quality applications than with the traditional Windows API. I think the equivalent is linux UBUNTu

In GUI i think no one can defeat Vista but in functionality Suse or Red hat is good.
