What impressed me about Win 8 CP and this RP was that after installing it, I just turned on my ethernet-connected Canon MX870 printer and Win 8 saw it and installed drivers. I didn't tell it to look for the printer, it just automagically detected it (over ethernet).
It took about 30 seconds. Impressive, IMHO. To be fair, the scanner isn't showing up at the moment but if I install Canon's Win 7 driver pack it will work just fine.
