How can I make the best of my ipod touch screen with no internet connection??

Question

I've been offered an ipod touch screen last Christmas and it's only a week ago that I took it out of its box. I still can't figure out how to transfer my music library from my laptop to the ipod. But I've installed some apps thinking I would be able to listen to my favourite radio station and play some games wherever I go and to my disappointment nothing's working if not connected to an internet connection. I thought an ipod was an improved walkman and actually it is nothing but a device that should be connected to the internet to work.
Considering that I don't have a free internet connection to the internet on my mobile phone, I was just wondering wht's the purpose to have an ipod? I really consider to go back to my old walkman... Thank you for your comments to help me to make the best of my Christmas present.

Answer 1

The message you are getting is saying that the iPod was previous synced to another computer. You can only sync with one computer. If you sync to another computer then the iPod media from the iPod get erased (as the message says) and is replaced with what is in the iTunes library of the second computer.
Syncing means copying (syncing) media from your iTunes library to your computer)
iTunes: Syncing media content to iOS devices and iPod       
For not showing in iTunes:
- Try entering the screen lock passcode on your iPod if not done already
- Go to Windows Device Manager and see if there is any problems/unknown devices
- Can you not import photos from a digital camera? The iPod appears in My Computer like a camera does.
