I am very interested in the iPod Touch, but I'm slightly hesitant with the whole iTunes thing. Hopefully, I can be reassured. 1. My sister has an iPod right now. Can I use the iPod Touch without getting a whole bunch of her songs on my iPod (and vice versa)? 2. Can you add album art to a song that you did not get from iTunes or from ripping a CD? I don't want that cool iPod Touch interface to be brought down because of songs with unknown album art. 3. Can you rip DVDs onto an iPod with iTunes? If not, is there an alternative way?
