Dust can still get on the sensor via the zoom, even if you never take the lens off.
I've had stubborn dust that wouldn't come off with my rocket blower and I've had to resort to sensor swabs - it's not hard to do, but it also isn't that easy or quick, either. And yes, you can PS out spots to some extent, but for me personally, the dust-off feature seems like a nice one and worth a premium,
if it actually worked.
