What killer app linux needs.

Earlier today I was using Ubuntu and was wondering what linux needs to make more people want to switch. What I think it needs is a free iLife like suite. If they could offer the same usability of iLife for free I think that would bring more followers. If linux could have Amarok interact with FSpot and so on. Linux is a capable OS and all that is needed in my oppinion is for the developers of this software to work together more. People often switch to OS X because of the look and for iLife or atleast from the people I know that have switched. Now linux with xgl can have the look and all we need is an free iLife clone. I could get into other stuff that needs to be changed for more to switch, such as a gui becoming standard for every application, but that's a longer story. Tell me what you think.
