Ok it really comes down to your preference pretty much. The Curve has a FULL QWERTY keyboard as opposed to the SureType QWERTY keyboard on the Pearl. Pearl isn’t that hard to get used to, but it can be frustrating when it gives you a word you didn’t even want. Size of screens, bigger on Curve obviously. And more memory on the Curve….I can only answer that you get the Curve for the 3 reasons I listed above. Because those are the reasons I switched from the Pearl to the Curve after only 2 months…;)
