Not all apps need a single thumb and not all apps need full/wide screen. But different kinds of apps may happily coexist in a single device. If I use a dial pad, 4.6" screen would be an overkill so I am fine if it is confined within 3.5" area. However if I watch hd video, 3.5" is silly. I would also prefer to browse with as much real estate as possible.
