I type e's instead of r's all the time. Well, not that specific error, but various off-by-one errors come up, especially when I'm typing quickly.

But here's the thing - as I'm typing, the screen is also showing me what the phone's best guess is for what I'm actually trying to type. If it guesses right, I can just hit space, and it'll replace the word, and I can go on typing. I've gotten pretty fast at using this feedback to type at reasonable speeds on the screen.

YMMV, but it sounds to me like you fell into the standard trap of "I meant e!" and hitting backspace and trying again, when often you can just forge ahead and the phone will get it right.
