The Guardian’s excellent iPad app has been updated to make it cleaner, faster and easier to use. The Guardian is the one Newsstand periodical I pay for because, even though you can get almost all of the same content on the website for free, the app is outstanding.

The new version makes it even better. However, there is one huge omission: support for the new iPad’s Retina Display.

It doesn’t take a huge stretch of imagination to picture some of the ways that the iPad can be used in the workplace. The idea of it as a sales tool, an electronic medical chart, and as a digital textbook device all come immediately to mind as common on-the-job iPad uses. But the iPad’s versatility lends itself to a variety of industries and jobs that you’ve probably never considered.

One example is agriculture management from the cab of a farm combine – one of the unexpected places to find the iPad that Hard Candy Cases CEO Tim Hickman mentioned to me during a recent conversation. His company, which also produces the ruggedized Gumdrop Cases, has received bulk orders for iPad from some surprising sources and has led to iPad adoption  in places beyond where most of us would expect. I decided to follow up on that conversation with some research of my own.

With all of the questions surrounding the new iPad’s battery life and heat temperatures, users will be comforted to learn that Apple’s latest tablet can serve as a mobile LTE hotspot for a staggering 25.3 hours. That means you could technically use your iPad’s Personal Hotspot feature for more than a day on a single charge.

Popular multitasking tweak CardSwitcher has been updated to version 2.0 in Cydia for iOS 5. If you remember Palm and the webOS platform, the look and feel of CardSwitcher will be very familiar. For jailbroken iPhones, this slick tweak brings the card-like multitasking environment of webOS to iOS.

If you want a change of pace from the tiny app switcher Apple has implemented when you double tap your Home button, CardSwitcher 2.0 is something you want to consider. There’s also an included multitasking interface that iPad users will enjoy.

If you know your Apple history, you’ll probably know that NeXTSTEP, the grandfather of modern OS X, had a clever feature called the Shelf, a placeholder where you could temporarily drop files while dragging them from one location to another. Sadly, Mac OS X has never replicated this in Finder.

So today there’s a brand new app for OS X that seeks to fix this. It’s called DragonDrop, and you can buy it for five bucks.

Developer Mark Christian released it independently today after weeks of trying to get it into the Mac App Store. Apple weren’t interested, and rejected it every time.

Is your iBooks library starting to outgrow those beautiful bookshelves that Apple provided for you? Have you purchased way too many Jim Butcher novels, only to find them crowding out your beloved Harry Potter collection?

Well, there’s a simple way to manage a burgeoning iBook collection, and we’re here to tell you how.

Earlier this year Apple announced iTunes U, making it clear that Apple intends to make the iPad ubiquitous in academia. The iPad is truly coming into its own as a legitimate alternative to the PC. For students, this means that the iPad is quickly becoming a powerful learning tool, which is good for a lot more than reading.

I sat down with a Boston-based PhD student who, for the past year, has been using her iPad nearly exclusively for her studies. Here are the core peripherals and apps that she recommends in order to supercharge your iPad for use in the academic setting.

Apple CEO Tim Cook was in Beijing today, meeting Chinese officials as the Cupertino company eyes up further growth in China. It’s his first trip to the country since he took over from Steve Jobs as CEO, and he got himself noticed with a visit Apple’s Beijing store where he stopped to pose for photographs with fans.

LTE is one of the key features available on the new iPad. All that extra speed can be a great feature for consumers and business users alike, although the ability to burn through data that quickly means that all LTE iPad users need to be more conscious of their data use than with the previous 3G iPads (the same will no doubt be true for the next iPhone).

A new study claims that most iPad Internet access (94%) still takes place over Wi-Fi networks, however. That seems like bad news for carriers and it sounds like comforting news for CIOs and IT professionals worried about unknown iPads in their companies. After all, if only 6% of iPad connections occur over 3G/4G, then most iPads in the office are using a corporate network and can be tracked and monitored to ensure data and network security.

Unfortunately digging into the actual data from the study reveals iPad users with 3G and LTE models are actually spending a lot more than 6% of their time using their cellular connection.

Steve Jobs coined it: the “Post PC Revolution.” But is this revolution actually occurring? Are people flocking en masse to tablets, forever leaving behind their keyboards and mice?

And what about those rumors that we’re going to see a 15-inch Macbook Air this summer? Is Apple on the verge of releasing the first pro-edition of everyone’s favorite paper-thin notebook?

We answer these questions and more in episode 5 of The CultCast, now ready for your listening pleasure.
