Ok I know this is old (they were released about a month ago) but I just spotted them whilst surfing. There's some pretty cool new tools included this time around. eg they have finally added virtual desktop support to the os (although its not as good as stardock's bandvmm), there's a new calculator that can plot graphs as well as the XP version of the infamous TweakUI.
IMHO definately worth a look.
