The device has disappeared from the Google Store, where a note in red type said, "no longer available for purchase," reported The Verge.

The Asus-made tablet was launched in July 2013 and remained attractive because Google kept it up-to-date with the latest versions of Android.

Nexus 9 has a 8.9-inch screen with 4:3 aspect ratio. On paper, it looks like an incredibly powerful device. It is powered by Nvidia Tegra K1 processor, which is a 64-bit quad-core processor running at 2.3GHz.

It has 2GB RAM. The screen has a resolution of 2048 x 1536 pixels. The device has an 8-megapixel rear camera and 1.6-megapixel front camera. It has 6700 mAh battery.

However Google describes Nexus 9 as a tablet that 'is for work and play, with its just-right 8.9-inch screen and front-facing stereo speakers'.

Other highlights of the phone include a powerful dual core processor Nvidia Tegra K1 and a sleek body with metal frame. It runs on Android Lollipop, as per the announcement by Google.
