personally, extra volume is not the only reason I've tended to use an extension cab, (with my Marshall MB4210) it also looks better having a bit of a stack (more rock and roll ) and also it takes the amp up to ear height which means you can hear it more clearly

I'd agree with that and you also get a little more feel with more air being pushed.
I don't think it makes me want to play any louder, just gives me headroom and feel.
