Just ordered an 8530 from VZW online to replace my 8830. Love my 8830, but I'm on my 4th trackball failure in 2 years and just don't want to deal with balls any longer. Was holding out for a Tour 2 with Trackpad, but I can get the Curve for free now. Pretty much a no-brainer.
From what I've read here on the forum, I think I will be very happy. Oh, hell, at this point I'll be happy with anything that doesn't have a trackball!
