I second that. I had a Dell Inspiron with the GeForce4 440 Go (GF2-based) but then ATI a couple weeks later started shipping the Mobility 9000 chip, which would have absolutely blown the doors off what I had.
If you can find a laptop with the 9700 (or wait for the GF 6800 Go), get that. You won't regret it.
