I've always really liked Paige. I took it off my list for good when my brother had a Phoebe. I figured cousins named Phoebe and Paige would be too Charmed for the same family. :)
I don't know any Paiges well, but I have met people with the name. I also knew a Mary Paige (double name).
The meaning is definitely "servant," I think specifically one who attended a knight as part of his own training for knighthood. I prefer the Paige spelling, both because it's what I'm used to seeing as a female name and because it distances the name a little from the words meaning medieval servant or paper. In all honesty, though, when I see Paige, I don't think of servents or pages from books; I just think of it as a name. Page has sort of a split personality for me. As a word, "page," I think of pages from books. As a name, "Page," I do think of knights and tournaments.
