It feels as if few months were already passed awaiting Android 4.4 KitKat update, though the official release announcement of KitKat version merely aged few weeks. LG Nexus 5 is the first device sporting the latest taste of android, but many parts of the globe have yet to fit in the timed release window of the device. Inspite of the hectic schedule for Google, it managed to roll out Android 4.4 KitKat update to Nexus devices, particularly, Nexus 7 and 10. The update is available via OTA, but is limited to WiFi only model of Nexus devices i.e. cellular (3G+4g) models users will have to wait for few more days until the update is available for them as well. This is kind of disappointing for Nexus 4 users as the wait is killing them. One of the primary reasons for getting Nexus devices is to get the latest flavor of android at the earliest. Nevertheless, Nexus users always hold the first position for sporting latest version of android. 
- Android 4.4.1 KitKat update is available for Nexus 7 (1st & 2nd generation i.e. 2012, 2013) and Nexus 10 WiFi model only.
