A good, not overly technical, overview of how multiple data sources are combined to improve GPS performance. This explains why Apple was saving data which could be used to track phones.
The article's topic is a very recent and relevant topic, but it has also been reported on over and over. The writer does however provide a decent article that can be understood by most any reader. The author shows initiative in his writing. I would recommend this article.
This is good journalism because I understand how to use the technology. The author explains how to use the GPS and Wi-Fi capabilities and the benefits. After reading the article readers will graps the usefulness of satellites and hotspots will allow location within seconds.
