While I agree, Apples attitude is a bit fucked up, they do explicitly state that older iPods are not supported under windows.
We are talking the old 5gb moddles etc. The new moddles work fine. So basically, you have people doing things you aren't supposed to do with the device, and subsequently breaking it.
Now, I would rather Apple have a more overt warning to users. Such as, plugging in an older iPod, the machine will pop a dialogue saying it is risky etc.
However, it's not a blatant abuse. It's simply not Apples fault people did what they were not supposed to.
It sucks ass tho.
