which console?

hi,

I'm posting this in all three of the proprietary forums to get your views.
hope thats ok?

i want advice on the best console for my situation if you don;t mind, and be biased if you like, as i'll read them all and be grateful.
I've a preference for first person shooters and strategy games, but the wife is fairly easy going as to what games take her fancy. also, i want an all rounder if thats possible.
I would appreciate any advice, and if you'd like more specific info about anything, so as to advise, please ask away.
they've become fairly expensive, and i've not been looking into them for a while, so would like the pointers so as to maximise the value from the purchase, one only coming to the house if you get me?

thanks
