Yahoo! China has the barometer on just how the recently released Nokia Lumia 920 is faring worldwide, as well as the lesser endowed sibling, the Lumia 820 – where they reported that more than 2.5 million units of the Lumia 920 and Lumia 820 have been either sold, pre-ordered or booked. This particular report arrived after Nokia launched the new Windows Phone 8-powered Lumia range officially in Hong Kong. In fact, it took just minutes before the Lumia device was sold out on Amazon China – could it be due to the lack of anticipated supply, or is it just overwhelming demand? Are you also going to jump aboard the Lumia bandwagon in the US as it has already arrived? If you are in two minds about whether to pick up the Lumia 920 or not, perhaps after reading our rather in-depth review, you might be able to come to a decision between the head, the heart, and of course, the wallet.
