Windows Migration Assistant for OS X Lion 1.0
Apple has released Windows Migration Assistant for OS X Lion 1.0. Much like Migration Assistant on the Mac, this new app makes it possible for users of Windows XP (with Service Pack 3), Windows Vista, and Windows 7 to migrate their profile and user data from a PC to a Mac running Mac OS X 10.7 Lion. (Free, 2.78 MB)
Would have been even cooler if you could use the migration assistant to pull the entire PC in to a bootcamp partition.
