At the WWDC this week a poll was taken place where any of the developers could cast their vote. This poll was solely on the App Store for the iPhone and iPod Touch. 50% of the developers said that they will switch over and focus on developing applications just for the iPhone and iPod Touch. The other 50% said they will still be creating Mac applications and developing applications also for the iPhone and iPod Touch. Some have said that 15% of the apps will take advantage of the iPhones location services, 10% will be related to entertainment, 10% will be video games, and 15%  will be other Enterprise-level apps. AppleInsider found that  the average cost of iPhone apps from the App Store would be $2.29 and 71% of the apps will be free. At this time I would also suggest to buy some Apple Stock because of the App Store coming out very soon. Investors have said that this could be a 1.9 billion dollar service in one year.
