Asus issued a companion dock for the Google signature tablet Nexus 7, which blog reports said will first hit the Japanese market within December, with the likelihood of a global rollout to follow shortly.

As per Android Community report, this latest Nexus 7 accessory will allow for a more comfortable use of the bestselling tablet. User can also sync and charge their unit through the dock's micro USB port.

While resting on the dock, the Nexus 7 can also be connected with an audio player or a headset via its 3.5mm audio out provision.

An unboxing video was posted late last week via YouTube, which is viewable on this link: http://www.youtube.com/watch?v=X4CjB37tdRE&feature=player_embedded. It is widely believed that the Nexus 7 dock was purchased a day before the product's Japanese debut.

Possible price tag for the dock is about, $US40, which reports said should be reasonable enough despite the absence of HDMI connectivity.

The Google tablet has been gaining considerable attention as more telcos around the world started picking up the slate, further pushing down its already affordable price, which the internet giant paired with top-notch hardware specs and a stock version of JellyBean.

Last week, UK's first 4G network EE added the 7-inch tablet to its growing stable of gadgets. Thanks to this Orange and T-Mobile consortium, the powerful device can be had for a one-off payment of between £30 and £50 plus monthly charges that will be determined by monthly data allowance.

Note that the Nexus 7, along with the Nexus 4 and Nexus 10, are not LTE-capable but thanks to EE's LTE dongle, the device will be able to access super fast internet connection via Wi-Fi connectivity.

As proof to global consumers' growing interest with the tablet, BGR News reported last week that Nexus 7's shipment is expected to exceed three million units by the end of December 2012, citing data from DigiTimes.

By the end of the current month alone, Asus would have shifted over one million of the tablet, easily surpassing its November total shipment of around 900,000.

Judging from tech experts' generally positive assessment so far and the sales numbers it has been generating since it was launched by Google, the Nexus 7 continues to reinforce its reputation as the most popular Android tablet, at least in the 7x-inch class.
