Detachable flash give many things, some of the basics are: 1) more power 2)further from the plane of the lens- less red eye, flattening of the face etc 3) can be removed and use and slave (some) for multi-directional lighting 4) don't drain your camera batteries 5) look cool 6) add better red AF light 7) let you do strobing

yeah, basically it gives you more options; depends on what you take photographs of/how much you wanna spend

Beside those mentioned above, external flash also gives you:
- more power to reach further away.
- zoom head which disperse the light when shooting wide angle, or concentrate it for further reach if shooting telephoto.
- adjustable head for performing bounced flash.
- high speed sync that allows higher shutter speed.
- better clearance to avoid casting shadow from some zoom lenses.

Better go read more first.

Strobing refers to lighting up scenes with external flashes, often they are used off camera via remote or wires.

Zoomhead refers to the flash which has a zoom function, the flash power can be magnified for further distances.

Slave device means it can be used as a companion to other light sources. I.e. Some camera's o-board flash can be used as a commander to trigger an external flash as a slave device.

For some Nikon lenses such as 18-200 lens, the built-in flash is unable to "climb higher" and results in sem-circle shadow at the bottom of the image when the built-in flash is fired. Problem is overcame by mounting a flash onto the DSLR hot shoe.

Therefore, an additional flash is necessity and not a "image making exercise". :)
