sam definitely has the disadvantage of being, in her own words 'the girl'. which when you're the only real female on the show, other than fraiser, it's natural you're going to be seen as romantic fodder for the guys.
personally i would like to see more of her and teal'c too, something i thing the actress has been quoted to want as well.
right now( really minor season 4 spoilers ahead)
she and daniel seem to be paired up a lot more than usual. and those of you who have see season 4 will know why.
all in all, i adore the character of sam carter. a female character in a sci-fi show who isn't there: a) for a love interest to eventually be killed off, b) male appeal(read 7 of 9 here) and c) just cause an all male show is boring.
