Chromebooks Come With A Best Before Date
Did you know that Google provides 6.5 years of Auto Update support for devices, after which you hit the Auto Update Expiration (AUE) Date. That date is not tied to when you purchase the device, but rather the initial release of the device. Once your devices AUE Date hits you will get no support, no updates and if you happen to use the Google Admin console you will not be able to access those devices like you could before they went stale.
The Register offers you a way to check when your time is up, especially important if you purchased an older model on sale or second hand. This is perhaps a little less devastating than on a machine running Windows, but still …
This means there will be no more automatic software updates from Google, no technical support from Google, and "business and education customers... should not expect that they can manage their devices as expected using the Google Admin console".
