"Me too!" post.
For years I swore I hated phones without physical keyboards. Then I picked up a Lumia 720 just for kicks. OMG. WP8.1 Word Flow was absolutely amazing. I was completely sold that I'd never need buttons again (except camera, plzkthx). Even extremely complicated words or those with letters in the same row almost always worked. If it didn't catch it the first time, backing the word out and putting a short, deliberate pause on each letter worked every time.
Couple months ago moved from a 735 up to 950. Thought, hey, maybe they'll also have fixed the one or two little mistakes the keyboard still makes, and that thinkpad nub looks sweet.
Still haven't fully posted in the 950 review thread because, holy &@^$^ $^&!&^%! This keyboard is a worthless, steaming pile in comparison and I just can't get over it.
1) As someone put it very well above: it has the vocab of a 12 year old.
2) It now
inevitably fails hard at words with letters in the same row, and it still does
not figure those words out, even if you try again with long, deliberate pauses.
3) It gives incredibly high preference to the name of anyone in my contacts over ordinary words, even when it's painfully obviously incorrect for the context.
4) It wants to capitalize the stupidest things. Like, why does it
always want to capitalize "So"?! (This is not related to
#2 for me, afaik.)
5) The keyboard as an input device seems to not be treated the same in all contexts? Easiest example is Facebook App (Beta). I know the app is parsing text to see if you're inputting a friend's name. But somehow this interferes with autocorrect and other functions in a way I don't ever remember the 8.1 keyboard behaving.
It really makes me appreciate the magic sauce that was the WP8.1 Word Flow keyboard. Much as I like a lot of the extras in W10M, I miss the old keyboard so badly I'm thinking of dropping back down to my 735. At this point I've almost completely abandoned using swipe gestures for any word longer than 5 letters, and I won't even bother starting to write emails longer than a sentence until I get back to my office computer. /rant
