It has not been my experience that autocorrect has become better: it has simply become more lax. As an example, I would actually find it really useful if the iPhone's autocorrect was smart enough to realize that my fingers were slightly off position as I typed (due to the lack of physical feedback) and could figure out what word I meant to type. However, it seems to just be running a spell check; it doesn't even realize that if I mash at the screen four times I intend to have four letters and it should not autocorrect what I typed to a word with five letters because it seems to be spelled similarly. The result is that a slight offset on the keyboard doesn't get corrected: it gets mutated into something hilariously unrelated to what you intended to type. Meanwhile, it also doesn't bother trying to come up with any kind of confidence rating for words I type that it doesn't understand. As an example: if I sit there and type a word with one finger, carefully moving my hand slowly to each key and carefully lining up each press, when I hit space bar the iPhone should realize "there is no way in hell I should be correcting this right now: this was a careful and deliberate action on behalf of this user", and yet even when you do that it will take a word and butcher it into one of the words in its dictionary; which, in the case of the iPhone, includes such words as "it's" and excludes such words as "its"... it doesn't even have the common decency to run a grammar check, something Word has had a reasonable-if-not-perfect implementation of for well over a decade now. Honestly: the iPhone has a /lot/ to learn from Word.

I was stubborn and tried to like autocorrect for a long time. My partner laughed when I gave in because she turned it off within 20 minutes of getting her new phone.

I found that autocorrect was intrusive and would interrupt my flow of words. The final straw was a few emails where I fought with it to get the word I wanted. I could have hit the X to cancel a change, but this required attention and it seemed hard to click in the right spot. It's easier to look for red underlines before I send an email.
