Have you ever seen an original Touch?
"Viva looks very similar to the original Touch.......... There have been a few improvements since then. There's now a minimum of buttons: a square navpad and call start/stop keys on the front, a power button on top, and an elongated volume rocker on the side. Along with a USB power/headphone combo-socket on the bottom....."
Takes out Touch. Ahem. Square navpad? Check. Call start/stop keys on the front? Check. Power button on the top? Check. Elongated volume rocker? Ok, give you that, it's a slider here and it sucks. Combo USB socket? Check.
So, they've changed the volume control and deleted the camera button then? Whoop-de-do for the improvements and all hail the minimalistic lack of a camera button.
Oh, I'd rather have WiFi than 3G any day. I travel a lot and 3G gives you roaming bills that would cause Croesus to think twice whereas I've never had more than a few minutes' trouble tracking down a free WiFi point to camp on.
