i've got them all
(got all of them double, besides the gamecube)
have to say for small kids and sportsfanatics get a PS2
for just kidgames or games that you will finish in a day get a gamecube
For more "complex" games and shooters and more adult (17+) games get an Xbox
for gameing on school get a Gameboy advance etc or a PSP
just my thought from a gamer since his age of 3.
i allready pre-orderd a Xbox360, Nintendo revolution and a PS3

just to complete the collection. (have all consoles and allmost all handhelds)
