To go back to quality again ... I really don't think many people want a keyboard (for general use as opposed to dev work) for the sake of having a keyboard, or if they do they'll be disappointed if they go back to one that isn't great.

Though having said this, legibility of the Jolla's screen in daylight is so poor, having ANY keyboard would be great for text entry when not dark / indoors.

Personally, I still dream about the awesome keyboard in the Nokia E71 (though obviously of a different type and layout).
