Affectionate cats are great because they can be held and snuggled on your lap. Dogs small enough to do that are often neurotic messes.
Our 60lb pitbull mix thinks she's a lap dog, although she's settled down and is usually content to be a "half on you head in lap"-dog now. Although she'll never be completely broken of the habit, as we've got a few relatives/visitors who enjoy having her there, especially in winter time.
She's doing very well with the kitten. Sniffing and licking it, then nosing it around, rolling it over into the crook of her legs and belly like it's a puppy. The kitten seeks her out for face-rubs.
Following normal cat development, she'll start running playing in another two weeks or so, and that'll be interesting.
Too early to tell for sure, but I think she'll be very laid back and social. She's gotten a flea-dip, and a few partial washings after the litter box without any cat-water freak-outs either. And does not struggle if you roll her over onto her back.
