Google Geospatial Announcements from Google I/O 2013: Should GIS Users Care?

Google announced new location services APIs, a new Google Maps and a visual refresh for Google Maps at Google I/O last week. There was lots of descriptive coverage from the mainstream and tech press. But there was very little response from the geospatial community - except from Esri. Who should or should not be excited about the new Google Maps and APIs?
