According to the CTIA, there are more than 246 million wireless data-capable devices at large in the U.S. today. Of these, 40 million are smart phones or PDAs, and more than 10 million are laptops. Little wonder that wireless data service revenue rose 31 percent to more than $19.4 billion in the first six months of 2009.

Revenue will no doubt continue that trend in the months ahead as wireless devices become more ubiquitous. Wireless carriers, then, would be wise to put some of their windfall toward building out their networks to cope with future demand lest they end up the butt of a joke in a rival’s advertisement.

Consider these remarks from Federal Communications Commission Chairman Julius Genachowski, spoken Wednesday at the CTIA wireless industry convention in San Diego: “We are fast entering a world where mass-market mobile devices consume thousands of megabytes each month. So we must ask: what happens when every mobile user has an iPhone, a Palm Pre, a BlackBerry Tour, or whatever the next device is? What happens when we quadruple the number of subscribers with mobile broadband on their laptops or netbooks? The short answer: We will need a lot more spectrum. The biggest threat to the future of mobile in America is the looming spectrum crisis.”

“A study conducted by Microsoft Research shows that consumers can process results with images 20% faster than text only results,” Microsoft’s Todd Schwartz explained. “So it’s clear that images play a big part in helping consumers with a variety of search activities….Visual Search allows you to quickly scroll through the galleries or do a one-click refinement using the quick tabs on the left, which are specifically relevant to the type of results you are browsing through.”

Think of Microsoft’s innovation as iTunes Cover Flow for search. And though it currently works only for mainstream queries (celebrities, dog breeds, iPhone apps, FBI’s Most Wanted, etc.) it’s quite impressive. And if Microsoft (MSFT) works quickly to extend it beyond its currently limited purview, Visual Search could do much to differentiate Bing from Google (GOOG). Certainly, Google doesn’t offer anything quite like it at the moment.

In fact, according to a new $6 million dollar study by the Virginia Tech Transportation Institute, texting while driving increases your chances of crashing by 23 times (see table below; click to enlarge).

Apparently, drivers take their eyes off the road for an average of 4.6 seconds when composing text messages–enough time at typical highway speeds to wreak all manner of havoc.

“Texting should be banned in moving vehicles for all drivers,” the study concludes, adding that it “has the potential to create a true crash epidemic if texting-type tasks continue to grow in popularity and the generation of frequent text message senders reach driving age in large numbers.”

We need a $6 million study to tell us this? Why hasn’t texting while driving been banned already?

Pages, Apple’s word processing application, is also getting a bit of an update. Pages ’09 offers a full-screen view for the easily distracted writer, dynamic outlining, mail merge with Numbers–Apple’s spreadsheet program–and 40 new templates. Not the most exciting stuff, here, but decent additions nonetheless.

In Numbers, Apple (AAPL) has added some new categorization features–Table Categories, and, answering user requests, some 250 new formulas and functions. New charts, trend lines and other advance reporting options as well.

iWork is also migrating from the desktop to the cloud–in a sense. Via iWork.com, users can easily upload documents and share them with collaborators. Docs are viewable online. They can be downloaded. And collaborators can comment on them online. iWork.com is cross-platform (Mac and PC) and cross-browser. The online suite looks very much like the Mac-based suite.

iWork will run you $79, $49 if you purchase a new Mac. “This is the beginning of a new service,” Schiller noted, adding that it’s a beta and launches today, solo and as part of a $169 box set that includes iLife and Leopard.

Adobe (ADBE) has conceived of a way for search engines to index Flash content, even pre-existing Flash content, without the need for developer intervention. It’s made content encoded in the Flash file format (SWF), which was previously undiscoverable to search engines, discoverable–and it’s given Google (GOOG) and Yahoo (YHOO) the tools necessary to discover it.

As Ryan Stewart, an Adobe evangelist, explained: “We are giving a special, search-engine optimized Flash Player to Yahoo and Google, which is going to help them crawl through every bit of your SWF file. This Flash Player will act just like a person would in some cases. It will click on your buttons, it will move through the states of your application, get data from the server when your application normally would, and it will capture all of the text and data that you’ve got inside of your Flash-based application. We’ve basically provided a very powerful looking glass into SWF files so Google and Yahoo can pull out meaningful information.”

Google will begin doing that today; Yahoo, whenever it manages. A big change for both companies, especially Google, which has long advised Webmasters concerned about their PageRank to use Flash sparingly. “In general, search engines are text based,” the company explains in its “Creating a Google-friendly site” FAQ. “This means that in order to be crawled and indexed, your content needs to be in text format. This doesn’t mean that you can’t include images, Flash files, videos and other rich media content on your site; it just means that any content you embed in these files should also be available in text format or it won’t be accessible to search engines.”

Today that changes. And now, developers can use Flash to their hearts’ content, without mucking about with workarounds to ensure the dynamic content it makes possible is properly indexed and ranked.
