The "New Xbox Experience" is stupid enough as it is: it takes up way too much space, shows very little of value, and hides most things well away from where you'd actually look for them. Basically, it's like Office 2007. And what a coincidence!
So now they're going to put ads on it. Even for paying members. (Yeah, it wouldn't surprise me if Office 2007 did the same thing eventually.)
The dumbest thing about it is that it's not like the 360 has a browser, so you certainly can't click through anything, and really, when was the last time you saw an in-game ad and thought neat, that's so cool, I need to go buy that stuff?
So now Silverlight will be drawing more cycles on the 360 (which is so awesome because there's no risk of it overheating, none at all) just to serve us ads.
jerks. Microsoft, meet backlash
