Off Topic, but I had a MotoX and couldn't figure out for the life of me what "Active Notifications" did that Apple's iOS Notifications didn't. I'm pretty sure I'm going to pick up a Nexus5 soon, but it still bugs me that I can't figure it out. I mean, if the phone is face down it doesn't display anything on the screen. I get that. It's kinda clever. But it's so minor I have a tough time calling it a "feature" much less a compelling one. Otherwise I was more annoyed with the MotoX notification system than anything. When you get a notification your unlock slider changes position. If you get more than one you can't jump to the specific one you want, only the latest. iOS didn't have either of these issues but it seemed like everyone considered Active Notifications somehow revolutionary. Or at least state-of-the-art. And it felt like neither to me. So I dunno. Going off on a tangent I guess. Just curious what I was missing is all...
