thats an option.
What bugs me about the alarm is that when it rings for quite a while (I'm a heavy sleeper) and you have set a couple of alarms, and let the second one kick in, it to starts to ring (still no biggy cause its supposed to wake you up). So when I finally get up and dismiss the both alarms, and I unlock the device the home-screen doesn't respond. The live tiles are still moving, and everything seems fine, but I cant select anything, I can lock the screen again, and undo the screen lock again but the home-screen won't respond, so I have to reboot the device.
Hope they'll fix this in the next update
