I'm using Gboard keyboard on my phone and you can swipe over the letters to type. I find it pretty good at guessing what I intend to say but I really should learn to proofread.
I just told Facebook that DD's room was "thirsty obese" instead of "tidy once".
Another friend recalls a time when she's was glad that she's did proofread or she might have accidentally sent a text saying her husband was dead. I can't think now what that was a typo for.
I also remember an interesting thread where people were encouraged to see what result they got if posting a status consisting entirely of the white that predictive text gave for 20 traps on the middle suggested word. It made good reading!
