I've used them all and THE fastest and most accurate entry on mobile by far was the psuedo-t9 keyboard on the Blackberry 7130. It was so good that it was frustrating to use the full keyboard on later Blackberry models. I wonder how many people actually experienced this keyboard in the world, perhaps only in the thousands?* Seems they had a name for it, SureType: https://en.wikipedia.org/wiki/List_of_BlackBerry_products#First_SureType_models_(7100_series) https://en.wikipedia.org/wiki/List_of_BlackBerry_products#Fi... edit: ah I see it was used on other more popular models, too. Blackberry Pearl users should chime in!
