Hi Lorriman, I agree the F30 can be a great portrait camera due to its low light capabilities, but the sensor itself isn't physically that different in size from other compacts. Fuji just uses the area differently and hasn't packed in a ridiculous amount of pixels!
As for bokeh and background effects, the small sensor and short actual focal length used in the F30 and other non-DSLRs will generally mean it's harder to achieve that out-of-focus effect due to their inherently larger depth of field.
But if you zoom in, get close to your subject and seelct the widest aperture, you can get a reasonable effect.
If you want a really blurred background though, there's no substitute for a telephoto lens on a DSLR with a bright aperture. Here's a shot taken with the Pentax DA 70mm on a K10D at f2.4.
