I was too bored with melayan tetamu that I finally tried to test every available new features in Vista yesterday and today. Anyways these are the best thing I think Vista has to offer
Indexing ServiceForgot all those other Desktop Search crap. THIS IS THE REAL THING! I love how it's fully intergrated with the start menu. Quite fast too. It took me just 4 hours to index 80GB + 250GB + 60GB + 320GB of HDD. and all of them are nearly 85% full. Just remember don't ever index you pr0n or Hentai folder

It also is situated on the top right hand corner of your explorer windows, thus making searchng file really fast as you can search for files in the index for that particular folder only.
Snipping Toolwant to make a screenshot, but don't want to take the whole screen? Snipping tool is for you. it will let you select the area of the place you want to take screenshot. you can then either edit, copy to clipboard or save it as JPEG!
Windows SidebarIt's not the widget of the sidebar that I like, but the fact that it uses simple XML to make the widgest suggest that Microsoft might release a tutorial on how to make your own!!
Internet Explorer 7Faster than FF (2), more stable than IE6, and looks cool. What more can I say?
Taskbar PreviewTaskbar preview itself is good, but what about the fact that it will show animation if the program is working. thus you can easily check if you son's minimised WMP is playing pr0n
New Address Bar in ExplorerAt first I was suprised that they are no 'Up one level button' anymore, but after mistakingly clicking on the arrow in fron of every folder name, I found out why. This is a quite good and initiative way to navigate throught the PC
Intergrated Windows Explorer with folder viewIf you notice, there is a folder view for each Explorer Windows. Just click an the 'Folder' button on the left hand bottom corner.
HDD indicatornow you can easily tell if a HDD is nearing the full capacity
