Had no idea of the new functionality until now. Here are some thoughts, not all related to the current Beta.
1. On the first screen after pressing "Alarms" there are buttons for quick alarm and custom alarm, and an alarm volume slider. Maybe I have something not set right, but I couldn't see a way to cause the alarm sound to go off so that I could check on the volume. It seems so odd to have a slider volume switch with no way to hear the effect of that switch, that I think I must be overlooking something obvious. Am I? (And no, the "Mute" button is not on.)
2. After pressing Quick Alarm you get the screen that let's you specify the time and the alarm sound. Then at lower left is the Alarm OFF/ON button. The "off" and "on" indicators exemplify a very common UI mistake: users can't tell whether they're coming or going. By which I mean that you can't tell whether "OFF" is a status indicator ("the current status of the alarm is OFF"), or whether it's a function button ("press me in order to turn the alarm OFF"). I've already gotten confused by that ambiguity once myself -- and I pay ATTENTION to user interfaces! Maybe adding some text, like "The alarm is [ON or OFF]" would do the trick.
3. On the main control panel screen is the button for "Music." You might consider whether that's becoming more and more misleading: with the NOAA weather radio channel, pod cast channels, and the ability to dial up Internet talk radio, etc., much of what's available from that button isn't "music" at all. I'd find a button that said "Audio" a useful alternative, but I'm not confident that most people would, so I don't know what to substitute for "Music." "Sound" just doesn't sound right to me. Now that I think about it, maybe "audio" is the only suitable option.
Ok -- those are my quick thoughts.
