Today's Tech: Google launches Nexus 4 & Nexus 10 despite Hurricane Sandy, Amazon derides iPad mini, Windows Phone 8 news breaks

Before we get stuck into everything else, make sure you check out our live blog, currently bringing you the breaking Windows Phone 8 news from Microsoft’s event taking place right now in San Francisco. Get that open in the adjacent tab, and digest all the news below as we round up a very busy day on ITProPortal.

It's been a dramatic start to the week here, kicking off with the news that Google's eagerly anticipated Google launch event has been put on hold due to a potentially devastating storm. Hurricane Sandy, which the Weather Channel describes as "dangerous" and "life-threatening," is currently battering the East Coast of the United States, with New York – where the Google event was scheduled to take place today – predicted to be one of the worst affected areas.

Sandy is classed as a Category 1 hurricane and, in terms of size, is the largest Atlantic storm system of the last 25 years. At 10:00 GMT this morning (06:00 US EST), winds of at least 85mph were being reported, with flooding and snow thought to be among the cyclone's other impacts. In addition to putting Google's autumn product unveiling on hold, Hurricane Sandy has also closed New York's NASDAQ stock exchange, and grounded nearly 7,500 flights. The search giant has not ventured if and when its event is likely to be rescheduled, but reports indicate that Hurricane Sandy will continue to close markets and playgrounds well into Tuesday.

The cancellation has not stopped Google from unleashing the products that were set to be unveiled in New York however, with the company confirming the launch of the Nexus 4 smartphone and Nexus 10 tablet, as well as a 3G version of the Nexus 7 slate. The former has been co-produced by LG, while Samsung has further bolstered its tablet portfolio with the Nexus 10. Unsurprisingly, the devices come with some impressive specs that are sure to draw suitors when availability begins next month – so follow the link for the full details.

Amazon, meanwhile, has launched an attack on Apple's iPad mini by comparing it to its own Kindle Fire HD on its US retail website, highlighting the advantages of its tablet over the alleged shortcomings of Apple's tablet. The retailer says that even though its screen is smaller than the iPad mini's 7.9in screen, the Kindle Fire HD has a "stunning HD display with 30 per cent more pixels than iPad mini” which you can get at a price 40 per cent less (£159) than the iPad mini (£269). The tablet wars are hotting up.

Steering away from the product conveyor belt, and in the security world experts have been voicing their concerns over the increasing trend of placing voter registration databases online. Millions of US citizens have been able to register for their say in the Obama-Romney presidential tussle via the Internet, which some say puts the information at the mercy of hackers. Groups like Anonymous have been claiming greater and greater scalps of late with their network breaching mischief, so can we really afford to be taking something as sensitive and important as voting details to the fragile domain of the web?

Elsewhere, an IBM research team has managed to build carbon nanotube field-effect transistors (CNTFETs) 100 times more dense than have ever been built before – huge progress in the search for silicon chips’ successor. The researchers developed a method to accurately position the cylindrically arranged lattices of carbon atoms in individual trenches, achieving a density of one billion nanotubes per square centimetre. The process is currently not marketable but is compatible with existing chip-manufacturing technologies. CNTFETs have the potential to get significantly smaller than silicon chips.
