My desktop has been Debian testing since Jessie. I was inconvenienced a total of 2 times where something broke and made an app unuseable. My KDE menu was fixed within a day and my torrenting app took longer to fix, but I was able to apply a one line fix in the meantime with help from our awesome community.
I know it's named "testing", but I'd bet it would be very stable for most people's use cases and trade off is absolutely worth it if people would give it a try.
I'm sad to say that those advertisements worked on me. When a young man needs to buy an engagement ring, name recognition, albeit in a negative light, got me to spend money with them. I just went to the first place that popped in my head.
You're renting, not buying. When you stop paying... poof! Your music collection is gone.
Water sensor alarms.
If you have any doubts about the pipes in your house or have a feeling that water might enter your basement, sensors will help you sleep at night.
Water damage to your home is no joke. I know two separate homeowners who have had leaks from their refrigerator's plumbing (water and ice dispenser). The damage for each homeowner was quite extensive given how small the leak was.
Sorry for the late reply. Yes, I think it's better for desktop. Stable is truly targetted for servers and desktop users will only be mildy inconvenienced once in a blue moon.
