I like the 580, what I don't understand is how they can add all the bells and whistles and yet no 3G.
My guess would be, it is a Walkman phone so the consumers who buy it would presumably be less interested in data, it's more of a media phone. The Z750 on the other hand is SE's first quad band phone with tri band HSDPA, and impressive specs, I think scotsboyuk posted the details somewhere earlier. So this one is obviously more for data.
