I got one but didn't own a DS before so no comparison. The screen is amazing though. Bright yet still good black levels and good overall contrast and the color saturation completely exceeds my expectations. Simply and amazing device for what I, as an adult (rather than a kid having to save up allowance etc.) consider an absolute pittance. Good job Nintendo.
On a side note, does anyone know the general return policy on opened games. I bought the sims and opened it but I haven't played it. I think i'd rather have mariokart DS. I bought the game at Target and most likely, though not for sure, have the receipt.
