My wife likes 4e. She's been playing 3.5 for about a year or so, and finds it way to complicated. She prefers 4e because it's much easier to learn and she doesn't really want to spend the time to read all the 3.5 books.
She's played a Sorceror, a Bard, and a Druid/Monk gestalt in 3.5, so I guess that's pretty close to Psion's female players. And in 4e she really likes the Rogue, but hasn't complained about the lack of well... every class that she's ever played. In fact, she wants to convert her Bard to 4e so she can be a Rogue instead.
She likes Dragonborn, but only if they don't have boobs - and if they have tails, wings, walk on 4 legs, and don't wear clothes. In their current state she finds them unplayable, and prefers the elfy races.
