[SprintTouch08]

depends if you want to carry a larger phone or not. Its not much larger on paper but trust me in the hand there is a decent difference in feel and weight. Its personal preference but i found the Pro a touch too heavy and felt a lot bulkier than the Diamond despite the dimensions on paper.

Also i found the build quality of the Pro to be inferior compared to the Diamond's on 4 different Pro's. I eventually gave up and returned it, refusing to pay $270+2 years for something with poor build quality (raised dpad, chrome flaking off, poor quality earpiece, loose slider). All documented problems in the Pro section and dont let Pro fanboys tell you otherwise or that there is no problem, read for yourself- getting a "good one" is a total toss up.
