We all know that a Verizon iPad 4G and an AT&T iPad 4G won't ride on each others' LTE networks, because they've each locked the models that they sell to their networks alone. But what if you could work around these business-shielding limitations to surf 3G on another carrier's network?

That's exactly what one owner of Apple's new iPad is claiming has happened with the Verizon iPad. MacRumors forum member jsnuff1 noted that inserting an AT&T micro-SIM card into the device and updating the iPad's carrier settings to support an … Read more

As the latest iPad nears its official availability date of March 16, those who haven't preordered already are left in a quandary.

To no great surprise, newly placed Apple iPad orders now won't ship for another 2-3 weeks. So, should you try waiting in a line at an Apple store or retailer on Friday instead for your iPad fix? … Read more

LAS VEGAS--Not content to rest on the laurels of its recently announced A200, Acer today unveiled a new Iconia Tab tablet, featuring a screen resolution of 1,920x1,080 pixels (1080p).

Typically, tablet screen resolutions top out at 1,280x800 pixels, but thanks to the faster speed of quad-core processors (Acer didn't reveal which quad-core CPU the new tablet would be using), look for high-res screens like this (and even higher) to become a trend over the next year.… Read more

Just in time for Christmas, France's Aldebaran Robotics has upgraded its Nao humanoid robot, making it better at obeying orders for the big cleanup.

Nao Next Gen is the latest version of the popular research robot, and it's looking more and more lifelike.

The 23-inch droid has been outfitted with a 1.6GHz Intel Atom processor and two HD cameras linked to a field-programmable gate array for faster processing of both video streams. Intel Capital led a $13 million investment in Aldebaran earlier this year.

It also boasts better speech recognition with a program called Nuance, allowing Nao to pick out individual words in a conversation. … Read more

(Read our new head-to-head buyer's guide for an updated comparison between the 2012 13-inch MacBook Pro and Air.)

Just a few short months ago (in March, to be exact), we wrote about an odd glut in Apple's otherwise streamlined lineup of products: instead of one or even two 13-inch laptops to choose from, Apple was offering three. The white MacBook, the MacBook Air, and the MacBook Pro each had a slightly different value equation in terms of design, features, and price.

That glut's been lessened a little now that the white MacBook has been discontinued. The MacBook Air and the MacBook Pro are the only two MacBook product lines left, and they represent two different solutions to same problem. The unibody aluminum Pro used to be considered thin, but it's--relatively--thick at 1 inch, and weighs over 4 pounds. The Pro offers better specs, while the Air, which has just been recently updated, leans toward light weight and quick booting as its advantages.

There's more to consider, though: the 2011 13-inch MacBook Pro and new 13-inch MacBook Air have become more similar than they've ever been before, for several reasons: performance, battery life, and a Thunderbolt port.

Two 13-inch MacBooks: which do you choose?… Read more

MIT researchers are working on an algorithm that could help reduce the likelihood of airplane collisions in the sky, part of work to overhaul the FAA air traffic system.

The FAA's NextGen overhaul mandates that by 2020 all commercial aircraft broadcast GPS coordinates, which would be more accurate than ground-based radar.

The system uses GPS data to track hypothetical puck-shaped zones around smaller aircraft to keep them a safe distance apart. Thousands of small aircraft were involved in near-misses over the past decade and there were 112 midair collisions, according to MIT.

Researchers at the MIT International Center for Air Transportation (ICAT) based the system on months of real-world flight data. A chief goal was to reduce the frequency of false collision alarms. They decided to use two alerts: a moderate one when flight paths are converging, and a severe alert when a collision is imminent. … Read more

OK, honestly, this is my last post on E3. While this year's show is over and we've seen both surprises and disappointments, another year looms: and with it, we hold out hope that next year's show can deliver on some unanswerables that this year's show conveniently skipped. At least, that's the way I feel. No show can ever hope to bring everything we expect--mainly, because E3 is only a collection of demonstrations from an industry that's constantly evolving--but as I peer into next year's crystal ball, this is what I hope we find.

Games and reasons to buy the Wii U Nintendo's next console, the Wii U, remains shrouded in mystery, in the middle of a year where Nintendo remains in a larger cloud of uncertainty. The Nintendo 3DS feels like a disappointment, and the Wii is in decline. That touch-screen tablet-of-wonders that Nintendo's hawking is a project with no definitive must-have games or applications, and that will need to change next year.… Read more

Could prefab structures be a quick and cost-saving way to get U.S. students out of dilapidated and energy-sucking schools?

A recent award to a Gen7 school building, made by American Modular Systems, seems to signal that modular classrooms have moved beyond being ad hoc building solutions for developing nations.

For the first time in California, a prefab building has been awarded national Collaborative for High Performance Schools (CHPS) certification for new school construction. CHPS certification is awarded to those schools that meet specific health, comfort, maintenance, and environmental sustainability standards.

"The Gen7 classroom proves that a prefab structure … Read more
