who has M14x, M17x and M18x? why?

i'm asking cuz i have two and i'm considering M17x, the missing member of the trio.

M18x is simply too big and heavy to take to the office occasionally.

M14x, while 650M provides decent FPS for the games I play, i yearn for slightly a bigger screen.

hence the m17x... at least that's what i've been telling myself...

(and we all have OCD, right? :) )


anyways, i'm curious if any of you guys have all three models and if care to share with us why you ended up with all three...

cheers
