Using Ipod library as the main music library?

I have roughly 20gb of music on my laptops HD and a further 40gb on an ext. HD. I would like to have all of this music in one place: my Ipod, and nothing on my computers HD (as this is taking up valuble space). I’m using the latest version of itunes and am finding that, when my ipod is plugged in, I am unable to listen to tracks directly off my Ipod. I’m sure that earlier versions of itunes allowed me to do this.

I do not want to have to carry around my ext HD with me when i travel with my laptop but don’t mind carrying my ipod. Ideally, I’d like to ve able to have No music on my laptop, but be able to plug in my Ipod and listen to music through Itunes. Perhaps I’ll have to give up Itunes for Senuti?

Any idea’s?

Try going into iTunes and setting your iPod for "Disc Use". Its only a guess but that worked to allow me to use iDump direct from the iPod. You could also try using an other player instead of iTunes. Download.Com has some good offerings.

Also you may consider using some Travel Speakers docked directly onto your Pod. Its a low tech solution, but it works!
