I had to go back to T9 whilst travelling in the US (no pay as you go for smartphones) and even after 3 months I still struggle. My muscle memory is never going to be as good for T9 as it is for a keyboard, writing symbols is a pain in the ass, the dictionary is much smaller (I always have to add proper nouns like Reno) and I can't switch languages/alphabets.
