This is my review of Android 4.2 Jelly Bean. Your mileage or experiences may vary as I can only base this on how this update has affected my Galaxy Nexus after the OTA update (on a phone that was having a few issues, so was probably due a factory reset anyway).
Minor update?
This update came a little out of nowhere. The software came out to coincide with the release of the new Nexus devices - the 'direction of the OS' hardware, produced with Google's direct guidance by the OEMs. Each new Nexus device has coincided with the release of a new version of Android, those releases being named after sweets and puddings (gingerbread, honeycomb, ice cream sandwich...) most of these have been "dot upgrades" in that the version numbers have increased by a whole number, or a decimal and had a new tasty name.
