I think it is important to remember that ATM is a network too,
like IP, and is not just a link technology.
Functionally, though, I think that the issue is more one of
"connection oriented" to "connectionless". The flexibility of
the connectionless packet switched network has allowed existing
media to be used at the link layer.
In many cases, this has allowed IP's uptake where ATM has not
been able to be deployed.
