Google's Nexus portfolio of devices seems to be on route to conquer the consumer market. The search giant's LG-manufactured Nexus 4 smartphone is already creating waves and now, per reports, the Nexus 7 tablet is set to exceed the 1 million unit sales figure for December.

As the demand for the smaller 7-inch tablets increases, the Android-powered Nexus 7 (made by ASUS) offering from Google continues to grow from strength to strength. According to Web site DigiTimes, its sources have disclosed that the Google tablet is poised to surpass more than 1 million sales in December alone.

"Global sales of the Nexus 7 are on the rise from 500,000-600,000 units a month initially to 800,000-900,000 units in November, and are expected to exceed one million units in December, according to Taiwan-based supply chain makers," reported DigiTimes

The growth in sales from 500,000 - 600, 000 units per month to 800,000 -900,000 units in November can largely be attributed to strong holiday sales. Holiday shoppers who are on the lookout for a budget-friendly tablet are turning to the Nexus 7, which was recently revamped by Google and now comes in a 32GB 3G-enabled model as well. The newer Nexus 7 models also feature the latest Android 4.2 Jelly Bean out of the box.

Earlier in October, ASUS' CFO David Chang had let on that Nexus 7 sales were nearing 1 million per month.

"At the beginning, it was, for instance, 500K units a month, then maybe 600, 700K. This latest month, it was close to 1 million," David Chang told The Wall Street Journal.

Reports indicate that, nearly 2 to 4 million Nexus 7 tablets would have shipped by Q4 2012 and December will be the first time Google manages to surpass the 1 million monthly sales landmark, since its July 2012 launch. By October end, Google had sold an estimated 2 to 3 million units of the Nexus 7, taking the total year-end sales figure between 4 to 7 million, overtaking its year-end target of 3 million.

By contrast, per DigiTimes, Amazon and Apple are slated to ship 3-4 million and 3.5 million Kindle Fire's and iPad mini's , respectively, between November and December. Interestingly, the increase in tablet demand coincides with a slide in notebook shipments.

With Christmas knocking at the doorstep, the Nexus 7 is gearing up to rake in the dough. Consumers, however, will be hoping that the inventory for the Nexus 7 does not run out unlike the Nexus 4.
