Despite Apple’s (AAPL) attempts to single out the Nexus 7 as an inferior tablet to its iPad miniGoogle’s (GOOG) 7-inch slate continues to sell very well, especially now that it starts at $249 for a 32GB model. According to Digitimes, global shipments and sales of the Nexus 7 are expected to exceed 1 million units in December, up from between 800,000 and 900,000 units shipped in November, as notebook sales continue to slide.

Quanta Computer, a supply chain company based in Taiwan, says it expects to ship “2-3 million Nexus’ ” in the fourth quarter this year.

Digitimes also notes that 7-inch tablets are seeing “booming sales in the peak sales period before the year-end holidays” with iPad mini orders seeing overwhelming demand. And while Amazon (AMZN) doesn’t release actual sales figures for its Kindle Fire tablets, Quanta said it expects to ship “3-4 million Kindle Fires” in Q4 2012.
