Pros: Sound quality, battery life.
Cons: Nothing is easy. It will push your frustration to the redline.
Summary: I hate my Sync. Nothing is easily done, not even basic stuff. Every function requires too many keystrokes, as you drill down through arcane menus. This is my 6th phone, and I have never been more frustrated. Retrieving last calls, txt, and the camera all require multiple key strokes and menu selections. I think it was designed by someone who never used a phone before. If I could afford to, I would throw it in the ocean. I often let my friends try it out, and they also think it stinks.
