With Mighty Meeting, all you need to deliver a presentation is your phone. You can upload your PowerPoint or Keynote presentations to your MightyMeeting account and then play them via your mobile device. The app is free, and so is the service, which is still in beta.
Mobile devices running Google's Android operating system are becoming more popular all the time. As of last February, Google reported that it and its hardware partners were shipping 60,000 handsets a day. In the first quarter of this year, Android smartphone sales accounted for 7 percent more of total smartphone sales than Apple's iPhones and iPad did.
The growth in phone sales has led to an explosion of apps for Android-based devices. At the end of last month, bloggers for the online Android app browser AndroLib estimated that there were about 83,000 active applications in the Android market.
