The most recent HP sets turned my wife into an AFOL. Now she's parting out a 10187 VW Beetle, and intends to buy the T1 camper. She also has about half of the architecture sets.
We've talked about th problems TLG has when it comes to reaching girls.
There have been a number of other sets that have caught her eye.

Most of these sets have a common thread. And that is that they depict normal human beings or animals working together in a social setting. They are either having fun, or being productive.
She universally goes, "Meh" at anything that is fire or police. Anything SW - GASP !! Bionicle or sportscars. But she gets hacked off at the sets that TLG markets directly to girls. For the same reason that she gets hacked off at a lot of the stuff in the "pink zone" of the toy isles. Which is, (and this is to quote her) that a lot of toys marketed to girls encourage them to develop a helpless outlook on life, where all they have to do is be pretty in order to be successful. And that it encourages them to believe that all they should do is be pretty.
Some other things that she says, "Why do they think everthing has to be pink in order to be interesting to a girl? You know, girls just like bright colors - and Lego's got all sorts of bright colors. "
At the same time though, she's super excited about the pink astronaught with the Farah Fawcet hair. And now she wants a pink spaceship to go along with it.
