"With six different versions of Vista due once it ships, figuring out an upgrade path can be confusing. Microsoft has tried to clear things up with a 4x6 matrix laying out your options. 'In short, users of XP Home can do an upgrade install to any of the four Vista versions. However, XP Pro users can only perform upgrade installs to Business or Ultimate.' And if you're not running a 32-bit version Windows XP, there's no upgrade path for you at all."

"Windows Vista will have a new 'previous versions' feature when it ships next year. According to Ars Technica, the
feature is built off of the volume shadow copy technology from Windows XP and Windows Server 2003. Now turned on by default, the service stores the modified versions of a user's documents, even after they are deleted. They also report that you can browse folders from within Explorer to see snapshots of what they contained over time. It can be disabled, but this seems like a privacy concern." From the article:
"Some users will find the feature objectionable because it could give the bossman a new way to check up on employees, or perhaps it could be exploited in some nefarious way by some nefarious person. Previous versions of Windows were still susceptible to undelete utilities, of course, but this new functionality makes browsing quite, quite simple. On the other hand, it should be noted that 'Previous Versions' does not store its data in the files themselves. That is, unlike Microsoft Office's 'track changes,' files protected with 'Previous Versions' will not carry their documentary history with them."
