Their newest ads are pretty awesome. Surface's dancing ad http://www.youtube.com/watch?v=iB5txqIl8jQ, the IE9 dubstep http://www.youtube.com/watch?v=GFE4rkSaKOY, the IE10 troll http://www.youtube.com/watch?v=lD9FAOPBiDk, and the various Windows 8 international musical ads (the wave after the countdown ad) http://www.youtube.com/watch?v=xurEdYsEne4 http://www.youtube.com/watch?v=giZcbCh4CtU and http://www.youtube.com/watch?v=vvHin1UmQOI are definitely a step way up from previous ad campaigns that Microsoft launched.

All in all, the Windows 8 ads are IMO fresh, and definitely leaning more towards the younger adult hip side. And they're pulling it off pretty nicely.
