Why not put a big flash built into a camera? Think of it this way:
look at what a big flash looks like. It's a sensor down low,
batteries in the middle and a flash on top. That's pretty much it.
You never see the sensor on top and the flash on the bottom. It's
because all kinds of bad things happen when you put a big flash near
the lens. In fact for weddings and such, everyone uses an arm to get
the flash-head higher yet. That's the first reason.
The second reason is cost. Say you have a $200 p&s with a big flash
built in. But a EX580 goes for something like $500. So you now have
a $700 p&s camera, You've just prices yourself out of any sales.
