In that game I mentioned which has the Urban Ranger, we have several casters in the party- including two spontaneous casters. Both of them have Dispel, and use it frequently- in fact I can't remember a session in the last three months that didn't see at least one Dispel cast by a party member (or an enemy).
Dispels are often not the best thing for a prepared caster to make ready, but on a spontaneous caster they're golden.
