Eh, I think I'm a gamer that, like the majority, doesn't care too much about fancy specs. I just care about fun games B-)
The console that I'll buy will be the one with the fun games. In the past this has always been the Gamecube but now I've been left feeling a bit stranded. I get bored of most of their games (eg. MK

, SM: Sunshine) pretty quickly and they don't have a lot of genres that I really enjoy - specifically RPGs and Aussie sport games. The PS2 has a plethora of games in those two categories.
So, as for the next gen of consoles, I'm not sure which I'll buy yet. I'll probably stick to Nintendo though.
