Well, I have a Zune and I like it. It's been reliable and produces decent quality music. I lost my first one (In Copenhagen airport) and was happy getting antoher one. And I can avoid iTunes!
And yes you can get the Zune to be recognised by the PC - do some searching and you would find that out. As for not recognised, it's because you did not load the drives on the machine you are plugging it into. I see this in my laptop (I have the Zune associated with my home desktop PC) but the device does charge which is all I want.
HTH.
