I'm increasingly skeptical about ubuntu. I transferred some music files from an iPod to rhythmbox and it seems to have worked fine but sometime during the couple hours of using ubuntu several things started happening. 1) 5 icons disappeared from the launcher leaving a grey button ( that button still opens the program), icons also disappeared from the dash home box and there is no volume control thing on the top right bar (with battery and connection icons) 2) the settings icon in top right was unresponsive and would not allow shut down 3) when I downloaded the latest30 updates the launcher icons all reverted to a large size after having spent hours on this forum getting help to use a script to make them smaller.
