The first release of Microsoft's Surface tablet computers will be Wi-Fi-only, two unnamed sources told the Washington Post.
When the tablets were launched Monday, Microsoft did not say whether the initial release of the Surface tablet on Windows RT or Windows 8 Pro would have cellular connectivity. Officials referred to a shortened spec sheet that left many details about the tablets unclear. The spec sheet lists both models of the Surface tablet as coming with various ports and a 2x2 MIMO antenna. Such antennas can be used in both Wi-Fi and cellular communications. Since the spec sheet was incomplete, it can't be assumed there will be no cellular connectivity, analysts said.

One informed source associated with a chip maker that's likely to provide chips for Surface tablets told Computerworld there wouldn't be a chip for a cellular radio connection in the first release. However, it wasn't clear what other chip makers will do.
The new iPad from Apple has 4G LTE cellular and Wi-Fi connections, although some models are Wi-Fi-only. Analysts for months have noted that Wi-Fi-only models sell better and make up the majority of the market, partly because many users don't want to pay extra for a cellular connection for a tablet as well as a smartphone.
Part of the Verizon Wireless Share Everything plan launching June 28 will allow customers with both tablets and smartphones to share the data service between them. That data sharing plan is expected to encourage interest in more purchases of cellular plans for tablets.
Some analysts say Microsoft will eventually want to offer a tablet with cellular service to expand the locations where the tablets can be used and have Internet access. Since tablets aren't as light and portable as a smartphone, which can be kept in a pants pocket , so users often find them easier to use within Wi-Fi zones in an office, coffee shop or at home.
The Post's sources also said Microsoft is using Pegatron Corp. in Taiwan to manufacture the Surface.
SEARCH engines have barely changed since Google was founded in 1998. Sure, they run on blazingly fast servers and are powered by sophisticated algorithms, but the experience itself is basically the same: users enter a word or two and the engine spits out links to the most relevant pages.
That is about to change.Last month, Google rolled out its "knowledge graph", which serves up facts and services in response to search terms - not just links to websites. It is the latest step in a process in which search engines are morphing into something quite new: vast brains that respond directly to questions posed in everyday language.
"Search does a good job of returning pages," says Shashidhar Thakur of Google. "But we can go beyond that and return knowledge."
Links are not necessarily the best way to answer a query. When I search for "location of Arsenal Football Club", for example, I would prefer to get a direct answer telling me the address of the club's ground in London, rather than a link to a document containing the information. Google and Microsoft's Bing can already provide direct answers to a small number of queries, but the range and depth of those answers is about to expand dramatically.
Over the past few years, Google and Microsoft have been quietly compiling vast knowledge databases to help them do this. Their stores have been built from publicly available information, such as Wikipedia pages, as well as prices from retail websites and user reviews. "All the things that describe an object are scattered across the web," says Stefan Weitz, director of Bing Search. "The challenge is to bring them together."

A backpack-size kamikaze drone ordered into combat by the U.S. Army could also soon become an aerial scout for U.S. Navy submarines hidden beneath the waves. Launching a flying robot from underwater utilizes a sneaky tactic — using a tube that normally ejects trash from a submarine.
The Navy wants the "Switchblade" drone designed by AeroVironment to become a flying scout capable of spotting enemy ships over the horizon, even as the "mother" submarine remains hidden underwater. Its upcoming submarine launch test would coincide with the world's biggest naval war games in 2012, according to a new contract awarded to U.S. defense firm Raytheon. Previous tests by Raytheon in 2008 showed how submerged launch vehicles can float to the surface and launch flying drones such as the Switchblade. But those demonstrations only involved surface ships and dummy drones.
The planned submarine launch would use the trash-disposal unit — the tube that typically ejects the trash of submarine crews — rather than one of several torpedo tubes designed to fire at enemy ships or submarines. Such a launch would take place with the submarine running just beneath the waves at periscope depth.
The Switchblade drone was originally designed to launch from a tube set up on the ground by a U.S. Army soldier, fly around until the soldier identified an enemy, and then dive at the target with explosive results. It's unclear whether or not the Navy wants the Switchblade to keep its kamikaze capability, but the scouting role seems far more useful for a submarine that already packs plenty of explosive torpedoes and missiles.
Any intended mission may become clearer during the Rim of the Pacific Exercise scheduled for 2012. That annual naval war game held by the U.S. and its allies in the Pacific involves plenty of opportunity for practice alongside ships ranging from carriers to destroyers and frigates.
If successful, Switchblade would join the U.S. military's fast-growing arsenal of robots at sea. The Navy has already begun testing a stealthy X-47B drone that could someday launch in squadrons from the heaving decks of carriers, as well as a Fire-X helicopter drone aimed at special operations such as catching smugglers or pirates.
