Mio: Win CE on board
Many PNDS (personal navigation device personal navigation devices) use Windows CE as the operating system, but this platform is not customized for this purpose. To meet the needs of equipment manufacturers, Microsoft recently announced that it will customize the Win CE embedded system navready 2009, which should be the first embedded system designed for GPS devices.

The year before, Google added many interesting features for Google Maps, such as GPS navigation. Although Google Maps in China is still relatively simple, the map of Google map in the United States can compete with professional map companies. More importantly, the cost of using Google maps is low. With the application model and promising prospects of another Google product Google Earth, Google Maps naturally becomes a heart disease for GPS professional manufacturers such as Garmin and

background running time. Some apps can request 10 minutes of extra time. A small number of apps do require unlimited background uptime, and iOS is allowed.
To be exact, in iOS5, there are 5 types of apps that allow unlimited background running time:
1. You can play the audio app in the background. For example, when Instacast is playing a blog.
2. You can track your location in the background of the app. For example, the TomTom navigation system makes
Gowalla, OpenTable, TomTom, Zagat, and Yellow Pages Group into a single database, allowing developers to access and obtain location information.
Twitter said that the extended database allows developers to easily provide users with more locations to mark, making it easier to associate Twitter messages with specific locations.
Although this is not a major news, it shows that Twitter continues to use location data as a means to strengthen its service
