LG Voyager or XV-6800? Why Wi-Fi?

[Kbcarpent]

I am new to the whole smart phone thing and am trying to get caught up on all the new features offered. I am a Verizon customer and plan to stay that way. I have been waiting for the release of the XV-6800, but after looking at the reviews on the new Voyager phone I am tempted to just go ahead and get it. The only big difference I see is the lack of wi-fi on the Voyager. Why do I want wi-fi if the phones connections are so good? Will I spend a lot more money on data transfer plans if I dont have the ability to use wi-fi? Hope to hear from some Geeks to help. Thanks!
