The wife has a Curve and I have the Pearl. She does a lot more email replies than me so the larger screen and keyboard work better for her. I use mine more for the phone and just scanning my emails. I like the smalle size to fit in my front pants pocket. She has a bag to put her toys in so size is less of a problem for her. Both are really nice and I think she would say she likes the Curve more than the Pearl but I like the Pearl more than the Curve. It's just how you use it that will make the difference.
