Piper Jaffray analyst Gene Munster today released the results of his semi-annual survey of U.S. teenagers, finding that iPhone and iPad usage remains strong among the 5,200 teens included in the study. According to the report, 48% of teens now report that they are using iPhones, up from 40% just six months ago.

We believe this demonstrates that Apple remains the top choice for teens despite more competition from Samsung. Additionally, the survey demonstrated that 62% of teens expect their next phone to be an iPhone, which we believe shows that the iPhone has loyalty amongst teens. In terms of Android, 23% of teens expect their next phone to be an Android device, up from 22% in Fall 2013. We believe that the Samsung Galaxy S3 and eventually the S4 are taking share from other Android devices, but little from Apple in terms of the teen demographic.

In looking at tablets, 51% of teenagers now report using a tablet, up from 44% six months ago. Of those 51%, 63% are using full-size iPads and 5% are using iPad minis, meaning that nearly 35% of teenagers in the survey are currently using Apple tablets.

For those teens that expect to purchase a tablet in the next 6 months, 68% said they plan on buying an iPad, thus it appears that Apple should be able to maintain its tablet share. The iPad Mini is beginning to show its impact as the 68% of those who plan to purchase break down into 54% for full sized iPads and 14% for iPad Minis. We would expect the iPad Mini to continue to cannibalize the full sized iPad in our continuation of the survey as we expect the breakdown in sales to reach 50/50 in the March quarter.

Samsung has attempted to play up its appeal with younger consumers through ads portraying the iPhone as uncool, with one ad poking fun at Apple fans waiting in line for the latest gadget by showing one Samsung user in the line actually saving a spot for his parents. But Piper Jaffray's results suggest that the iPhone and iPad brands remain strong with U.S. teenagers, with Apple undoubtedly planning for those users to become lifelong Apple customers as they become locked into the company's app and content ecosystem.

There are few great emulator options for OS X, but that is set to change in the near future as multi-source system emulator OpenEmu prepares for an official launch.

Open Emu is an open source project to bring game emulation to OS X as a first class citizen, leveraging modern OS X technologies such as Cocoa, Core Animation and Quartz, and 3rd party libraries like Sparkle for auto-updating. Open Emu is based on a modular architecture, allowing for game-engine plugins, this means Open Emu can support a host of different emulation engines and back-ends while retaining a familiar OS X native front-end.

OpenEmu, which has been in beta for quite some time, is able to emulate the hardware of several different consoles. Version 1.0 of the software will include support for several 16-bit systems, including the Game Boy, Game Boy Color, Game Boy Advance, Game Gear, NeoGeo Pocket, Nintendo Entertainment System, Sega Genesis, and Super Nintendo, among others.

Support for additional systems like the Nintendo 64, the Nintendo DS, and the Sony PlayStation will be added in the future.

The emulator features a slick iTunes-style design, displaying downloaded ROMs in a menu organized by system. Designed from the ground up for OS X, it offers up a native OS X interface.

With full save state support, the software allows for multiple ROMs to be played at once and it also provides OpenGL scaling, multithreaded playback, and gamepad support.

At this point in time the team behind OpenEmu is working on polishing the app and adding final artwork, but the release is "close."

OpenEmu was previously available as a beta download and the beta version of the application can still be acquired by downloading and compiling the source code via Xcode. A full set of instructions is available here.

Research firm IDC today announced the release of a new report covering the mobile advertising market, noting that ad networks such as those from Google and Apple are losing traction to publishers able to use their size to drive their own advertising sales.

Where in past years, ad networks such as Google, Millennial Media, and Apple received most of the spending on mobile display ads, now publishers control the segment, thanks to very strong sales growth in the past year. Facebook, Pandora, Twitter, and The Weather Channel all registered strong sales in 2012 and all (with the exception of Pandora) popped onto the scene from zero sales in 2011. As a result, publishers controlled 52% of U.S. mobile display ad spending in 2012, compared to the 39% they received in 2011.

IDC notes that, despite slowing growth, the mobile advertising market continues to boom in the United States, growing 88% in 2012 to reach $4.5 billion to provide a massive opportunity for ad networks and publishers alike. The report notes that mobile advertising now accounts for 11% of all digital advertising, illustrating the strong momentum of mobile.

Apple has long faced an uphill battle to gain momentum with its iAd service, repeatedly slashing buy-in fees in order to lure and keep customers unwilling to commit to expensive advertising campaigns limited to Apple devices. The popularity of Apple's devices did allow Apple to rise to the number two spot behind Google in mobile display advertising, but IDC notes that Apple ($125 million gross revenue) lost that spot to Millennial Media ($151 million gross revenue) last year.

Apple's iAd program grew out of its 2010 acquisition of ad firm Quattro Wireless. Quattro founder and CEO Andy Miller left Apple in mid-2011, and since that time iAd has been overseen by senior vice president Eddy Cue as part of Apple's umbrella of Internet Software and Services.

Among Apple's granted patents released today, AppleInsider has noted a pair of inventions that appear to be of some interest. The first patent addresses the idea of offline iTunes Store purchases from mobile devices, allowing users to store "credit" that can unlock content already on their devices but not yet owned by the user.

In some cases, a user may wish to add new media items to the library, for example from an online media store. When the device is not connected to the store, however, the user may not be able to perform a transaction to purchase new media items, nor download or access the media items from the store. To enable offline purchases of media, the electronic device can store locally for future use one or more recommended media items received from the store when a connection with the store is available. Access to the recommended media items can be restricted, so that the user cannot consume the media items without first purchasing them.

To complete a media item purchase without sending transaction information to the media store, the electronic device can store pre-paid credits locally on the device. The pre-paid credits can be purchased in advance, for example when the device is connected to the store. In response to a user request to purchase a particular recommended media item, the electronic device can deduct the cost of the recommended media item from the locally stored credit, and remove the access restrictions of the device. The amount of credit remaining can be communicated to the store or to a host device (e.g., used to manage the user's media library) when communications become available.

The difficult part of this scenario involves getting the content onto the user's device, and Apple's patent addresses several methods, including manual loading of files either from the Internet before going offline or from other storage devices. Alternatively, the user's device could automatically pre-download content based on Genius-like recommendations or other criteria and offer the content for on-device purchase.

While Wi-Fi hotspots have become increasingly common to allow iPod touch or Wi-Fi iPad owners to connect to the Internet with some level of regularity, it appears that Apple is still interested in exploring ways to allow users to unlock new media content even when not connected to the Internet.

The second patent describes a proximity-based method for transferring files between devices, such as a computer and a mobile device. While a number of existing solutions such as Bump and Samsung's S Beam allow for such actions, Apple's patent includes a contextual aspect that allows for very specific transfer scenarios to simplify the user experience.

In one simple example outlined by Apple, a user composing an email on his or her Mac wishes to add an image from their phone. Under the proposed method, the user could select the insertion location in the email, use a contextual menu to invoke an insertion option, bring up the desired image on their phone, and then bring the phone in close proximity to the Mac.

Using a combination of proximity and communication technologies such as Bluetooth, near field communication (NFC) technology, Wi-Fi, and or a webcam, the image could then be automatically and wirelessly transferred to the computer and inserted into the email at the proper location.

DigiTimes claims that Apple will begin volume production of the 5th generation iPad in July-August 2013. The timeline reportedly comes from sources in Taiwan-based supply chain makers.

Mockup of 5th Generation iPad next to an iPad mini

While Apple's traditional timeframe for iPad launches has been in the first few months of the year, last year saw two iPad launches -- one in March, and one in November. The late 2012 release of the 4th Generation iPad may have altered that usual timetable.

The new iPad is believed to be "thinner and lighter" than the currently shipping full-sized iPad. The 5th Generation iPad is also believed to take on the same thin-bezel design as the iPad mini. The above mockup is based on leaked iPad 5 enclosures from early this year.

WhatsApp business development head Neeraj Arora has told AllThingsD that an earlier report claiming Google was on the verge of acquiring the company for $1 billion is not true. WhatsApp is the company behind the popular iOS app WhatsApp Messenger.

Neeraj Arora, WhatsApp’s business development head, told AllThingsDigital today that the company is not holding sales talks with Google.

Arora declined to comment further, but AllThingsD does note that WhatsApp has been the subject of sales rumors before, having been linked to Facebook in December. At the time, WhatsApp said that those reports were "not factually accurate."

WhatsApp Messenger has consistently been one of the top paid apps in the App Store in many countries around the world and is currently the #1 paid app in the U.S. store. It is one of the many messaging services, including Apple's own iMessage, available on iOS and other platforms that smartphone users have turned to in order to avoid carriers' SMS charges.

Recently, WhatsApp announced that it will be moving to a subscription model for the iOS version of its app by the end of this year. The model would likely be similar to existing WhatsApp pricing for other platforms, which would make the app free for the first year and then $0.99 per year beyond the initial free period.

Citing supply chain sources, Digitimes reports that Apple is expected to see only modest "single-digit" shipment growth for its notebook lineup in 2013, with the 13-inch MacBook Pro in particular seeing weaker-than-expected sales.

Apple was confident about its 13-inch MacBook Pro performance for 2013, but the device's actual sales turn out to be weaker than expected, leaving the company still digesting its inventories in the first quarter.

The sources pointed out that Apple's MacBook Pros have strong attraction to consumers, but the devices' high prices are instead pushing consumers away.

The report also claims that Apple will be refreshing its notebook lineup "at the end of the second quarter", which could mean an introduction at the company's Worldwide Developers Conference expected in June.

Digitimes had reported in late December that Apple was planning a June refresh for its notebook lineup, and similar timeframes have been claimed by reliable KGI Securities analyst Ming-Chi Kuo and Taiwanese newspaper Economic Times.

Back in mid-February, Apple released a surprise minor update for the Retina MacBook Pro, including a significant price drop for the 13-inch models. Apple also dropped pricing on the high-end MacBook Air at the time, a move that had been at least in part predicted by Digitimes in its late December report.

Apple is likely to use Intel's forthcoming Haswell processors in its next-generation notebooks, and Intel will reportedly be releasing the first mobile Haswell chips in late May or early June.

Apple today began offering refurbished models of the current-generation 27-inch iMac for the first time, roughly four months after the models initially launched.

The two stock configurations of the 27-inch iMac are currently available at 15% discounts compared to brand-new units, with the low-end refurbished model priced at $1529 vs. $1799 new and the high-end refurbished model priced at $1699 vs. $1999 new. Several higher-priced custom configurations are also currently available as refurbished units, with all refurbished models listed as shipping in 1-3 business days.

The addition of refurbished 27-inch models comes nearly two months after Apple began offering refurbished 21.5-inch models, with supplies having remained tight for a number of months due to issues related to the thinner design of the new iMac. Apple is using a new lamination process for the display to achieve a thinner and more vivid screen, and that process reportedly was resulting in low yields, particularly for the larger 27-inch models.

Availability of the new iMacs improved markedly in early March, with shipping estimates for new orders of all stock configurations improving to "within 24 hours" at that time.
