Today's Tech: Samsung mulling metal Galaxy Note 3, HP ElitePad 900 review, and NAO set for 4G auction probe

HP's ElitePad 900 tablet is geared towards the enterprise market, combining the looks of a consumer tablet like the Apple iPad with enterprise friendly features that corporate users need. The Windows 8 device promises both portability and productivity, but how ell does it live up to its claims? Joel Santo Domingo took it for a spin to find out. If your business is committed to HP services and products through contracts, then the HP ElitePad 900 is a very good Windows 8 tablet for the SMB though enterprise organisation, he concluded. However, if you're with another system builder or are starting from scratch, Dell's Latitude-branded enterprise tablets may be a better choice. Follow the link to find out just what holds the HP ElitePad 900 back.

Disgruntled murmurings about the Galaxy S4's build quality may prompt manufacturer Samsung to use metal for its next flagship smartphone, widely expected to be the Galaxy Note 3. According to recent reports, the South Korean firm is "worried" that its devices are not regarded as highly as they could be by gadget buffs because of their polycarbonate construction. Apparently, the company flirted with a metal-bodied Samsung Galaxy S4, but ultimately decided against it due to manufacturing concerns. However, the near universal acclaim that greeted the aluminium HTC One and the respect traditionally afforded to the design ethos of bitter rival Apple has apparently given Samsung plenty of food for thought going forward.

In major security news, technical failures within the Pentagon's IT infrastructure have led to a mass data leak of defence documents and over half a million emails regarding the cases of Guantanamo Bay detainees. According to the lead defence counsel for the lawyer for Mustafa al Hawsawi - one of four men being tried over their alleged involvement in the 9/11 attacks - a "significant amount of defence work" was lost from a drive along with "over 500,000 emails containing attorney-client privileged communications", reports Frontline. US Department of Defense spokesperson Todd Breasseale later denied that prosecutors had seen confidential defence emails, telling the news site in an emailed statement, "I can tell you unequivocally that NO prosecutor and no member of the privilege review team saw the content of any privileged communications." But Breasseale admitted that "a nearly catastrophic server 'crash'...coupled with satellite latency issues" between US and Guantanamo-based computers caused "losses of indiscriminate data" across both the prosecution and defence teams.

The UK's National Audit Office (NAO) is set to probe Ofcom's recent 4G spectrum auction, after the bandwidth sale fell short of expectations by more than £1 billion. Concluded in February, the auction saw telecom giants O2, Vodafone, EE, Three, and BT splash out a total of £2.34 billion for space on the 800MHz and 2.6GHz LTE bands. But the sizeable cash haul was well short of the £3.5 billion estimate offered up pre-auction by the government's Office for Budget Responsibility. The NAO has confirmed to multiple sources that it intends to launch an investigation into the matter, and the forthcoming probe is understood to have originated with complaints made by Labour MP Helen Goodman, the shadow minister for media and communications.
