"Fluency on the iPad, like language fluency, does not necessarily come natural to most people. Unless you grow up in a language, as your mother tongue, and you acquire speaking this language unconsciously as a baby and child, it will require an effort (to various degrees) on your part to learn to become fluent in that language. Becoming fluent on the iPad requires a conscious effort and time as well."
