I also had the 8703e and exchanged it for the 8830 World Traveler. The 8830 blows away the 8703. The trackball is fantastic, the keyboard lighting is just fine. The ringer is a tad low but that depends on the ringer you choose. The internet is lightning fast, battery lasts all day with very heavy use, I am totally happy with the change. The voice dialing is really nice and helps so much when I am traveling. The option of adding a memory card is also a huge plus. I have all my ringers on the card as well as a youtube video that plays perfectly in full screen. I absolutly love the 8830.
