Look for Zune vs. Classic iPod, both of are right compete since iPod Touch is just newer, different than Zune and iPod Classic.
iPod Touch is similar to PDA without phone or cellular wireless function, both of iPod Classic and Zune are reality digital music player with video function, both of them use hard drive since iPod Touch use flash memory, flash memory is less feed with battery than hard drive does.
Right now, iPod Classic is quietly behind of Zune because of no WiFi and no touch screen, however you can compare with Zune and iPod Touch if you need opinion for that.
In previous post, for behind, I was means that Zune store is very behind of iTunes store, sorry for misunderstood.
