Well the 8700 is still a very popular model among power users. I think it's the best BB built out of the series. One of my bosses who upgraded to the Curve after her 8700 died, said to me (as I was gushing over how lucky she was to have the Curve), "you like this? I'd swap you if I could. I miss my old blackberry, I hate this."
I went from the 8100 to the 8700 so I can't really blame her. It has a solid feel, a keyboard that once you get comfortable with it you don't want to leave it and a very vibrant display along with a loud speakerphone, tough casing that can take a beating and still look great and amazing battery life (I don't even need to use my Seidio extended battery for it, just stock). If it had a camera I would just continue to ride with it.
IMO, it's worth more lol.
