Following the sudden discontinuing of the Nexus 5 from Play Store, Google has also recently taken down its mid range tablet, the Nexus 7.
Yes. If you are thinking of purchasing the 2013 Nexus 7, then it is sad that you may find the product page displaying 'The Nexus 7 is no longer available for purchase' message.
It is worth noting here that the Nexus 7 has received the Android 5.0 Lollipop update last year which had brought many features like multiple device compatibility, material design, battery settings, etc.
For now, Google Play Store is only selling the 16 GB and 32 GB variants of the Nexus 9 tablets. But, the 9 inch tablets may not be the right device for everyone.
