Wireless Connection After Installing OpenSUSE 12.3

Since OpenSUSE 12.3

got serveral decent reviews, I tried it with Gnome. Just like many complaints in OpenSUSE forum, there was no wireless connections. Fortunately after I restart right after the first Gnome, the wireless icon magically appeared along with battery icon. The wireless connection works.

Current Android and iOS Device Usages/App Launching Per Day

According to "Flurry Five-Year Report: It’s an App World. The Web Just Lives in It",  currently the U.S. consumer spends an average of 2 hours and 38 minutes per day on smartphones and tablets. 80% of that time (2 hours and 7 minutes) is spent inside apps and 20% (31 minutes) is spent on the mobile web. 

All mobile browsers combined control 20% of consumers' time. Gaming apps remain the largest category of all apps with 32% of time spent. Facebook is second with 18%, and Safari is 3rd with 12% Worth noting is that a lot of people are consuming web content from inside the Facebook app. For example, when a Facebook user clicks on a friend’s link or article, that content is shown inside its web view without launching a native web browser (e.g., Safari, Android or Chrome), which keeps the user in the app. 

The app economy is thriving, with The Wall Street Journal recently estimating annual revenue of $25 billion.

From left to right, we see that the average number of apps launched per day by consumers climbs from 7.2 in 2010 to 7.5 in 2011 and finally to 7.9 in 2012. 

The following chart shows that, on average, only 17% of the apps used in Q4 2010 were in use earlier in the year on a device compared to 37% in Q4 2012. 

That means that 63% of the apps used in Q4 2012 were new, and most likely not even developed in 2011 (or possibly poorly adopted). Flurry believe that with consumers continuing to try so many new apps, the app market is still in early stages and there remains room for innovation as well as breakthrough new applications.
