Asus has revealed that it is now shipping upwards of 1 million Nexus 7 tablets a month, reports the Wall Street Journal. It is the first insight into just how well the Nexus 7 tablet is faring, although Google has yet to reveal its official sales figures for the device. On launch the Nexus 7 quickly sold out of its initial product run, with its $199 starting price being one of its main attractions.
