Actually, I find that the mashing buttons to kill the baddies falls squarely on the Wii, while beer drinking FPS tournaments are 360's big thing, and heavily priced bizarre gameplay falls in the ps3 arena.
Regardless, the biggest issue seems to me to be basic economics. What is the cost of your entertainment. I've been interested in picking up a next gen console since the wii came out. I've played all three extensively, and at the moment, their price point is nearly identical. But for me to get one game out of a system, I need to drop about $300 for the base system WITHOUT any games, and $50 for a relatively old game (Mario Galaxy is still $50, 3 years in). With high quality games like Braid coming out on steam for $5-$20 the comparable initial drop of $20 to start playing and $350 to start playing is an obvious choice. Needless to say, despite the fact I've typically enjoyed console gaming for years, the higher price point for individual games combined with the cost of the systems (which haven't dropped to levels that I feel the purchase is justified), makes people who share this opinion swing away from them.
I still haven't swung toward cellphone games, because generally, across the board, I haven't found many of them that are on par with games from the super nintendo. Tetris maybe, but I haven't found a good solid push for thought provoking games for a cell. The biggest challenge for me is that the cost of old classics is finally pushing up into the current 'new game' price point that I have no interest in.
I'm mostly hoping this commentary will shed some light on the mindset of a, possibly atypical, non-hard-core gamer.
