Different neighbors, being on different circuits, being on a line that's more likely to have storm damages, can make a lot of difference in quality of power delivery.
I've lived in places where the power practically never went out, never experienced undervolt situations, etc. I've then lived less than a mile away from the same place and experienced seemingly monthly issues of all the clocks being reset at random times when I come home. Living closer to things like hospitals, fire stations, emergency operations centers, etc. seem to give the best indication of power reliability, at least from my personal experiences.
But then VideoGuide [1] was released (available from RadioShack). I begged my parents for that and honestly it was the most amazing product and worked flawlessly. I felt like I was living in the future.
who is right - no way to know, everyone can make their own judgement.

The last couple of VCRs we owned even had automatic time setting. It read extra data in the vertical blanking interval from our local PBS station.
I was surprised that kind of thing wasn't much more common earlier - it wasn't really any new tech breakthroughs so much as someone just going to the effort of building it.
