Today's Tech: Google-backed Motorola launches new Moto X smartphone and Android thrashes iOS, Windows Phone and BlackBerry OS

After months of rumours, Motorola has officially unveiled the Moto X, its newest flagship smartphone. It is "the first device that was built from scratch after the Google acquisition," Motorola Mobility CEO Dennis Woodside told reporters today, and is effectively the "relaunch of Motorola." The Moto X sports a 4.7in, 1,280 x 720 pixel display, making for a 316ppi density. The device will run Android 4.2.2 at launch; spokespeople did not have any timetables on a possible bump to Android 4.3, which launched last month on the new Nexus 7. On the inside, the Moto X sports the new Motorola X8 mobile computing system that includes several chips: a 1.7GHz Qualcomm Snapdragon S4 Pro, as well as a natural language processor and a contextual computing processor that handles the sensors, both developed by Motorola. Disappointingly, it has emerged that the smartphone will not ship beyond the US - check out all the details through the links above.

Online professional network LinkedIn saw a 59 per cent increase in sales for the second quarter, to $363.7 million (£242 million). LinkedIn also saw its net profit increase to $3.7 million (£2.4 million) from the $2.8 million (£1.8 million) it made in the second quarter of 2012. The current membership total of 238 million represented a 37 per cent increase year-over-year. LinkedIn said persuading luminaries such as Bill Gates and Richard Branson to get involved in its Influencer Programme had contributed to homepage traffic more than doubling compared with last year. "Accelerated member growth and strong engagement drove record operating and financial results in the second quarter," said Jeff Weiner, CEO of LinkedIn. "We are continuing to invest in driving scale across the LinkedIn platform in order to fully realise our long-term potential."

Billionaire investor Carl Icahn has filed a lawsuit against Dell and its board, in his latest attempt to block Michael Dell's bid to privatise the company. Icahn has asked the Court of Chancery of the State of Delaware to stop the firm from postponing a meeting set to take place today, at which shareholders will vote on founder and CEO Michael Dell's takeover proposal in conjunction with investment firm Silver Lake. Icahn also wants to stop Dell from changing the date by which shareholders needed to have bought their shares to be able to vote. He has also included an order preventing Michael Dell from counting any shares purchased since 5 February – the date that Dell first announced his buyout proposal - as part of the vote. Today's vote has already been rescheduled twice, with rumours indicating that Michael Dell was concerned he hadn't secured enough support at the time.

Google's Android platform is going strong, with a 65 per cent lead over all other mobile operating systems, according to new stats from Strategy Analytics. The report tips a growing global smartphone market, up 47 per cent year over year for a total 230 million units shipped in the second quarter. Android is the greatest benefactor of the uptick, having captured a record 80 per cent share of the global smartphone OS market. Strategy Analytics executive director Neil Mawston chalks the success up to competitive licensing costs, numerous hardware partners, and a large app store. Meanwhile, Apple's iOS reached a 14 per cent share this quarter — its lowest level since Q2 2010. Microsoft slipped into third place, with four per cent share — its highest in three years. The "others" category, which includes the BlackBerry OS, dropped from 10 per cent last year to a low three per cent, though the analytics firm offered no explanation for the steep decline.
