I actually just finished writing a book chapter for a well-known author you'll soon find out about on just this version of WSUS. Its a nice upgrade, and with WSUS' recent history of super-easy upgrades probably one that you'll soon want to apply. The enhanced bulk approval and performance upgrades alone are nice enough to warrant the upgrade, if even just to make your life easier in managing the system.
