WSJ – Like the Curve, the N95 has good voice quality, but runs on the slow EDGE network, though a future version could support faster networks. Unlike the BlackBerry, the current N95 also can use Wi-Fi networks. Battery life is only fair: 3.5 hours of talk time.
The Nokia N95 lacks a full keyboard, physical or virtual and its email is primitive. For $749, you could buy the Curve and a very nice digital camera. But the N95 is for photo enthusiasts who want an all-in-one device. The Curve is a more mainstream smart phone that aims for a balance of features at a low price. Link.
