lifterus:Seriously, you're complaint is based on eye-candy. All that matters is that it works. Yeah, I have VMC and selfishly would prefer it Vista only. But truly I really don't care. Accessing "Watch Now" titles without a keyboard and mouse is all I care about right now.
IMO, if you are going to do it, do it right. Seamless integration is important to the end-user's experience. WMC Presentation Layer provides such seamles integration.
As to eye-candy, don't underestimate how important it is. Our lives revolve around decisions we make based on eye-candy: from our clothes, to our cars, to our houses, to our furniture, to our girlfriends/boyfriends....
