I totally understand the desire to want something educational and electronic because she enjoys yours! She has years of electronics ahead of her, however, you might want to look at the Leapfrog products. My children have loved the Leap Pad, Tag books, and the Leapster when they were a little older.
At 2, my daughter's favorite things to play with were dress up clothes, puzzles, and babydolls. My mother got her a Disney Princesses dress up set that was fairly in expensive that had dresses, shoes and tiaras and she was thrilled for hours on end.
We also got her a play kitchen and she has cooked many meals for us since then.
If you live near a Learning Express store, I would recommend going in and exploring. Even if you don't buy anything there you can get great, age-appropriate ideas.
Happy shopping!
