I can understand why the desktop gets a pass, but I really, really wish they would consider doing it for sites which pop up those damned "Give us your email!!" forms. Especially those sites which pop it up almost immediately when I've arrived at their site for the first time. I don't even know your site yet. Just followed this link from somewhere else. And you're immediately demanding my email for your pointless newsletter?

Maybe it's just me, but I think I hate those things more than anything else on the current web. Maybe even more than autoplay videos.
