Your camera, while it isn't an SLR, is a lot more capable than you might thing it is! It can shoot up to f/2.8, which while it isn't great, isn't bad either. Shoot on apeture priority wide open at f/2.8 and I think you'll be surprised.
I have an earlier version of your camera (much earlier) and I've taken a few shots with shallow DOFs, like these (I think both of these are using the macro setting):
Or this one:

But obviously, there's a difference between any SLR and non-SLR...and it isn't just $$.
Also, what do you mean by "implying motion by zooming"?
