According to new data from comScore, 6.8% of Web traffic in the U.S. comes from "non-computer" devices such as smartphones and tablets. This is an increase from 6.2% in the previous quarter.

Phones account for the majority of non-computer traffic. Mobile devices drive 4.4% of total digital traffic, tablets contribute 1.9%, and other non-computer devices send 0.5% of traffic.

Why did Apple put out a press release today about reaching the milestone of 15 billion downloads? Maybe to distract you from the other news about how it just lost the rights to the term "App Store" in a high-profile lawsuit against top competitor Amazon.

Well, guess what? It worked! Look what our headline reads!

Still, it is an impressive number, and one that puts competing app stores to shame. And Apple had even more new numbers to reveal today, too.

Social media monitoring firm SocialNuggets was tuned into Apple's developer conference (WWDC) this week, and specifically the news revealed during CEO Steve Jobs' keynote address. The firm's goal was to see what Internet users had to say about all of Apple's new products and services.

To reach its conclusions, SocialNuggets monitored over 12,000 social media mentions, blog posts, forum postings and other online mentions. The results are not surprising. For the most part, the reaction to nearly all of Apple's announcements, from iOS 5 to iCloud and beyond, was overwhelmingly positive.

Google recently released an update to the Android Market which introduces a new feature for mobile developers: the Application Statistics dashboard. This tool lets developers better see details regarding their application's performance, status and trends, using charts, tables and other data. The information can be used to compare an app's trends with those found in the rest of the Android Market. It can also serve as a resource in determining what to develop next, says Google.

Worldwide mobile data traffic is due to increase 26-fold to 75 exabytes annually, says networking giant Cisco in its latest report, the Cisco Visual Networking Index Global Mobile Data Traffic Forecast for 2010 to 2015. To put that in perspective, that's the equivalent of 19 billion DVDs, 536 quadrillion SMS text messages or 75 times the amount of global Internet IP data (fixed and mobile data) in the year 2000.

It's also a major increase from Cisco's report last year, which forecasted an increase to 40 exabytes by 2014.

New data from stat-tracking firm Experian finds that U.S. Twitter users are now spending two hours and 12 minutes per month on Twitter.com reading and replying to tweets. That's up from one hour and 51 minutes last year. However, the time spent during any given Twitter session has declined. In November 2010, a typical Twitter session was 13 minutes, 12 seconds, down from last year's average of 15 minutes, 12 seconds.

This suggests that users are "seeking more frequent quick hits," says Experian, "rather than spending longer periods of time reading through posts."

While sitting around with a group of friends the other day, I took a quick, informal poll and asked "Hey, do any of you use Twitter?" These were friends I'd grown up with hacking code together, running BBSes and generally geeking out with. While all of them had accounts, they hadn't used them since they created them and they couldn't figure out why they would.

It was a bit of an eye-opener, as is the latest data from Pew Research finds that only 8% of online American adults use Twitter.

According to a new report from International Data Corporation (IDC), Apple has just passed RIM, makers of the Blackberry smartphone, to become the fourth largest mobile vendor in the world.

Prior to this quarter (Q3 2010), RIM held the number four spot. It's now at number five. Apple's move up the charts also ousted Sony Ericsson, which has now exited the top five altogether.

Since the release of the fourth version of Apple's iOS operating system for the iPhone, Microsoft's Bing can be used as the default search engine on the iPhone. So far, however, Bing has not been able to make major inroads on that device. According to a new study from advertising network Chitika, which recently launched its mobile ad platform, Google continues to dominate search on the iPhone. Almost 97% of searches on the iPhone originate from Google in Safari and the native Google app.

For many, the launch of FaceTime, Apple's video calling service for the iPhone and iPod touch, seemed like a gimmick with little practical usage. According to a new survey by the Pew Research Center's Internet & American Life Project, however, 19% of American adults have now tried video calling, video chats or teleconferences using services like Skype, Google Talk and Apple's iChat. Looking at the number of total Internet users in the U.S., this means that almost a quarter of them have now tried video calling.
