Actually I saw some great utilities on there, especially the "Time Machine" feature from Apple. Windows users have to use 3rd party tools like Symantec Ghost/LSR or Acronis True Image to get good snapshots like that. Apple is beating Microsoft at it's own game - intergrating as many features as possible into the core O/S package, which is what most users want. This also helps overcome Apple's lesser compatibility with commercial off the shelf software, they just build it all and package it with their systems.
Are you kidding? Backup and Restore in Vista performs the exact function you provide, and best of all it’s in VHD format so you can mount it.
