TIPA awards…as usual everybody wins :)

I always find these TIPA awards a bit…strange (Click here to see them). As usual every company wins at least one price. They created so many categories that is is almost impossible to not win something :)

Look at the four(!) mirrorless categories:
Best CSC Entry Level (Olympus PEN E-PL3)
Best CSC Advanced (Panasonic LUMIX GX1)
Best CSC Expert (Sony Alpha NEX-7)
Best CSC Professional (Fujifilm X-Pro1)

Didn’t know a camera can be for “advanced” users, or “expert” users or “professional” users. Somebody can lighten me up the difference?
