According to a study created by Chetan Sharma Consulting, mobile app downloads should jump from 7 billion in 2009 to almost 50 billion in 2012. By this time, the market will be worth 17.5 billion dollars, the study predicts, despite the expected lower price of mobile apps, which should drop from the current average of 2 dollars per app to 1.5 dollars in 2012.

GetJar chief executive Ilja Laurs makes another bold prediction, echoing the one we’ve recently heard from a Google (Google) executive. “It is easy to see how mobile apps will eclipse the traditional desktop Internet. It makes perfect sense that mobile devices will kill the desktop,” he said.

He backs this up with more data from the study, citing that 17% of GetJar users spend more time on internet-linked smartphones than they do on desktops.
