Well known Microsoft MVP – Marc Liron – has posted 26 videos on his new website that “preview” Windows Vista.
If you are looking to upgrade to Windows Vista soon then have a quick run through the list over at:

Most are only around 5 mins long but are very useful for getting a handle on the new and improved features of Vista.
