I'm making a judgement based on what I have seen. The PS3 is definitely geared towards teen and mid 20s males. The wii and nintendo in general seem to just cater for people who want to pick up a game, play and then put it down.
I quite agree with your comments. I was one of the first in line for an original psx, and more recently a psp. The psp has let me down personally. I wont get a ps3, although to be fair I wont be able to get one due to short supply and they are so expensive.
I never got a 360, although I still play (or use) my original xbox nearly every day for movies and emulators.
Sony dont rate highly in my book any more.. which is sad as I used to be quite a fan...
