It just depends on what you need the BB for. You want a BB that is going to meet YOUR needs. What is going to be your main reason for getting a blackberry?
Well I don't know who your cell phone provider is...but I would suggest going to one of their stores and playing with the curve and the bold. You need to get the phone that is going to meet your needs.
From what you just stated above...I think the curve would be great for you...it is a very solid BB.
