With its e-textbook initiative, iTunes U, and a range of educational resources, Apple is pitching the iPad as critical element in 21st century schools. Many schools have already begun iPad tests or full-scale deployments. In other schools, however, there’s still a fight over where and how the iPad and other technologies fit into the classroom. A battle erupted between teachers and lawmakers in Idaho earlier this year over new technology requirements in the state’s schools.

So what makes some schools embrace iPads and other new technologies while others resist them? It turns out that the answer may lie in the personal technology preferences of school and district administrators.

Titles like Angry Birds, Tiny Wings, and Jetpack Joyride have proven that popular smartphone games are big business for developers. But why are we so addicted to gaming on our mobile devices? Well, according to a new survey from MocoSpace, a third of us do it just to kill time and cure boredom, while 10% of us do it to meet new people.

AirPlay and AirPlay Mirroring add a lot of value to the second and third generation Apple TVs. Paired with a recent iPad or the iPhone 4S, an Apple TV can instantly become a gaming solution and a theater for home movies – and will be amazing when combined with Mountain Lion when it ships this summer.

AirPlay also turns that Apple TV into powerful and extremely portable presentation system that’s a great fit for the classroom or the board room. The only challenge is that the Apple TV’s only output option is an HDMI port, which can be a big problem for connecting to older display technologies including many projectors and computer displays – a problem solved by cable and adapter maker Kanex.

Virtually everyone who’s ever used an Apple product has an Apple ID. This user account for all things Apple is most commonly used with the iTunes Store and the iOS and Mac App Stores. It’s used to both authorize purchases and to allow you to access content or run apps after they’re downloaded. Apple’s philosophy is that every person should have their own Apple ID and that each of us should use our individual Apple ID (and only that Apple ID) on each of our devices – iPads, iPhones, iPods, Macs, even PC’s running iTunes or other Apple software.

That’s a great concept, but it creates a big challenge when iOS devices are used in business or school environments. When someone configures an iOS device for an employee or student with a selection of apps and other content (like iBooks 2 textbooks), they need to use an Apple ID. But once that device is deployed, the end user may need or want to purchase additional apps or other materials.

This is often a stumbling block for business-owned devices. And it’s something that Apple has finally begun to address with Apple Configurator.

Unlike most computers, the iPad isn’t designed to be a multi-user device. iOS doesn’t support multiple user accounts or profiles – that essentially means one set of device and application settings along with a personal collection of information like notes, email, browser bookmarks, and stored passwords for different online services. Sharing a device with that much personal data makes it easy for someone to snoop while using another person’s iPhone or iPad or on an iPad that is commonly shared between multiple users.

Passtouch is a web browser for the iPad that’s designed to offer at least some multi-user capabilities as well as to secure web-based information like bookmarks, cookies, and stored passwords. It doesn’t offer whole-device accounts or profiles but it does offer some extra security for devices that are regularly shared.

AirPlay Mirroring is one of the iOS features that Apple is bringing to the Mac in Mountain Lion. It’s a feature that offers a lot of potential for mobile professionals and educators in addition to being a great supplement to a family’s living room.

AirPlay Mirroring works the second generation Apple TV. The Apple TV itself as a small and easy to carry device that can plug into any HDTV or modern projector. That simple setup combined with a Mac running Mountain Lion makes for a perfect portable presentation solution.
