The sheer volume of available apps is one selling point for iOS. For those using the iPad or iPhone in the workplace, there is an ever-growing selection of business and productivity tools. Some of these, like the apps from Salesforce.com, tie into existing business solutions and are available at no charge. Others may not be free but fill critical business needs like those that provide the ability to view and edit Office documents (examples include Quickoffice, Documents to Go, Office2, and Apple’s iWork apps).

This presents a conundrum to some IT professionals. In business environments most desktop applications (Mac or Windows) are purchased using volume or site licenses and delivered to workers using mass deployment tools. The software, or more accurately the license to run it, is purchased as and remains company property.

iOS apps, on the other hand, are treated by Apple much like music tracks or TV episodes. They’re purchased using an iTunes Store account and can be installed on any iOS devices tied to that account. Essentially, they become the property of the person who has purchased or downloaded them. That flies in the face of traditional IT tactics – a point reported by Network World as a constant source of issue to IT departments and a point of discussion at the MacIT conference that ran alongside MacWorld | iWorld last week.

Did you know that it’s incredibly easy to turn almost any document into a PDF directly on your iOS device, with a simple third-party app? That app is called PDF Converter from Readdle, the developers of a number of popular productivity apps for iOS. If you’re looking for a free PDF converter for iPhone, you can find all the essential tools in this guide. Here’s how to do it.

We’ve waited patiently for this little gold nugget of a photo processing app to land at the Mac App Store, ever since developer Nevercenter teased us with CamerBag 2‘s beta a few months back. Wait’s over: It’s here. And today only it’s on sale for $19.

Did you ever wonder what Siri would look like, if she weren’t just a bunch of 1s and 0s bouncing around inside an Apple data mega-center? The Big Bang Theory’s Raj thinks she’d be a sultry, promiscuous sex line operator, but that’s not the only possibility, which is why the makers of the popular Nomad Brush Stylus have thrown a contest called the Compose Portrait Siri-Ies Challenge, in which they’re giving away a custom engraved Nomad Compose to the person who comes up with the best depiction of what Siri really looks like.

We’re totally digging the entries they’ve gotten so far, which range from beautiful to monstrous, from realistic to abstract. Check out the best faces of Siri below, then go over to Nomad to vote for your favorite.

For a lot of people, yesterday’s 10.7.3 update for OS X Lion went without a hitch using Software Update, but for a sizable (and understandably annoyed) minority, the update resulted in the widescale crashing of apps and the replacement of stock Lion UI elements with a mysterious “CUI?” error.

If you’ve been bit by this error, you have our sympathies, but buck up! In most cases, it’s a pretty easy thing to fix the update and get Lion working as it was.

It’s been a of couple years since the social food finding photogasm app Foodspotting hit the scene, and now — thanks to many hours of hard work — the guys over at Foodspotting are proud to introduce Foodspotting 3.0. In what they’re calling “Pandora for food,” Foodspotting 3.0 has received a complete visual makeover with a Pandora-like interface for discovering and rating dishes. In version 3.0, user can:

We’ve been covering the teaser trailers for Reckless Racing 2 in the run-up to its launch, itching to get our hands on the latest release. This is the sequel to the hugely popular Reckless Racing from Polarbit, and it promises to be even more incredible, with a new selection of 18 highly-detailed cars, 24 different routes, and new game modes. And it’s available to download now.

If you’re the kind of geeky person who experienced a little thrill of joy when the hacking scene in Tron:Legacy included realistic use of a genuine command line interface, you (or perhaps your kids) might also enjoy playing with Hacker Typer.

This is a guest post by Mike Daisey, who’s latest monologue, The Agony and Ecstacy of Steve Jobs, is at New York’s Public Theater through March 4. We highly recommend you go see it. It made Steve Wozniak cry. The post originally appeared here.

Stephen Fry, brilliant comedian, wonderful actor, and bon vivant just posted this in his Twitter feed:

As a fellow raconteur it’s painful to have to confront Mr. Fry with this fact, but he’s being a total idiot.

He’s in good company—most of the Mac universe is in the midst of a massive propaganda campaign, trying to convince itself and the universe that the cognitive dissonance they are feeling at this moment isn’t real.

So you’re going to see some good people, like Mr. Fry, who happen to love their Apple products very much, say some horrible things because they don’t actually understand how to reconcile the beauty and grace of their wonderful Apple products with the unvarnished, verified truth of how they are produced.

Last week we told you about Evi, an iPhone app that challenges Apple’s own Siri voice control technology. Powered by the same Nuance backend, Evi and Siri offer similar voice control/assistant features. The main difference between the two is that Evi is available on the iPhone 4 and iPhone 3GS, while Siri is only available natively for iPhone 4S owners.

Another App Store app has come to our attention, and its name is vokul. As the first and only 100% handsfree voice control app for the iPhone, iPod touch, and iPad, vokul allows users to dictate text messages, make calls, and play music without ever having to lift a finger.
