Autocorrect is more often slowing me down. It's only rarely correct.

Yep. Autocorrect's one of the first things I turn off on any device. I'd rather have a misspelled word than an entirely wrong word.

Case in point: people spelling "definitely" as (I assume) "definately" only to be autocorrected to "defiantly" without noticing. That sort of "correction" completely changes the meaning of a sentence.

This does not compute. I am a fast typer on all mediums, but a touch screen is just so slow compared to physical. I think I got around 80 wpm on my blackberry, there is no way I could do that on a touch screen. And iPhone autocorrect is terrible with any sort of tech jargon - frequently causing manual corrections.

it is just a habit. Here is a video from 2010 with 97 wpm on iPhone - https://www.youtube.com/watch?v=NNcTE5WJGdw

I've found that haptic feedback helps. My first smartphone was a handmedown first-gen iPhone, so I didn't really understand the point of haptic feedback because I wasn't exposed to it, but upon switching to a Galaxy SII and feeling a tactile response with each press I've yet to look back.

Every time haptic feedback turns off for "power saving" when I'm running low on battery, I immediately wonder how anyone ever manages to type anything at all without mucking things up all the time.

I'd still prefer a physical keyboard, though.
