There is no rubber bung on the c860. I think it is really durable and should last a long time with a little care. I suggest a pdair case, i was really impressed with my one.
Stubear, really? I got mine secondhand... it seems in perfect condition. Anyhow, i\'m not too worried i always keep it in my pdair case and not among the crap in my pocket! ;-)
