A handheld gaming system.
An upgrade to the previous GameBoy Advance.
Features a back-light,
a massive library of games(library spans 8 years),
and the games can easily be switched.
An attachment can be purchased so it can hold 4 games at one.
One of the best hand-helds to date.
Me:I just bought a GBASP.
Friend:Cool.I just bought one too!
