I don't have a console preference, I have a games and value preference.
Right now that puts me at about:
60% 360
25% Wii
15% PS3
Given its expense the PS3 doesn't justify itself based on the games available for me. If I become interested in Blu-Ray its likely the console's value will exponentially increase in my eyes.
The Wii's game library isn't as strong as the Xbox 360's but I place it ahead of the PS3 because it is far cheaper and does some cool new things.
