The Apple keyboard is junk, especially if you use it in swiping mode.

Swype on Android (and briefly on iOS) - RIP - was simply better in every imaginable way, but whoever bought it just buried it. Far better prediction (once they fixed the bug that interpreted a common swipe as "nee", which I almost never use, instead of "me", which I use constantly) and a host of useful features. Need to capitalize a word? Just Swype above the keyboard once during the motion. Need a double letter? Squiggle a bit on that letter as you move through the word. Swype-X, C, V for cut, copy, and paste. Swype-spacebar to bring up an editing keyboard that offered single-character cursor movement. Want to curse? Feel free, it won't forget it with the next version upgrade. Keyboard learned a typo? Delete it from your user dictionary and it won't appear anymore.

That was a startup. Apple could buy out any patents they had with pocket change. But they didn't, and I can't figure out why.
