I've enjoyed not having to buy an alarm clock for many, many years. A phone allows me to change the noise I wake up to and set multiple alarms at random intervals. I now rarely sleep through the alarms - no more hoping that the alarm clock had a good noise and no more suddenly finding out I no longer wake to it (and yes, I sleep through them: They'd wake up others in the house. Yes, this is even with good sleep hygiene.)
Music comes from tech, too. This is especially helpful to cover up small noises in my house or the apartments around me: The small noises disturb me more when falling asleep than a radio/television going on. (The same has been true of studying: A quiet library is an experience of interruption. So. Many. Noises.)
I've lived more than one place where my tech had to be in my bedroom if I wanted any sort of privacy while using it.
Much better to be diligent about using it. It sucks that the poster seemed to be doing this, and I understand their complaint. It seems to me that it is a software oversight, but like they said, "disturb" is the norm, so we probably won't get real relief until standards change.
