Besides having some apps simultanious open (2x xterm for latest autobuilder inspection and fast program installation) I have these 2 multitasking scenarios which need real multitasking:

1. RSS offline reading and online browsing
   I have several RSS feeds and twitter searches registered in the defaut RSS feed reader. When calling a link from within the reader microb is called. Then I switch back to the RSS reader and continue reading the feeds while let microb render the web page in the background. After a while I return to microb and read the web page.
   
   
2. Simultanious speech navigation and podcast listening
   Listen to a podcast while listening to the navigation system running in the background (and coordinate an incoming phone call or notification as well)

Hope that helps,
