1) Cisco ISL is much better than urgly 802.1q - first of all, it was
designed many years before 802.1q. I am not even talking abiout those
idiots, who designed 802.1q as a _spanning tree on the trunk level_, which
made many configurations (which we used with ISL ain 199x years) impossble,
and caused vendors to extend 802.1q.
2) Of course, VLAN does not infer routing. But VLAN routing can be provided
on the switch fabric, effectively bypassing many traditional drawbacks - see
Cisco 6509, for example.
