Many Android users love the third party Swype keyboard. Mobile users on iOS can only watch in envy as words appear while gliding a finger across the screen.

SwiftKey is looking to push the concept even further with its predictive Flow keyboard. You can register for the beta at that link.

Google recently updated the default Android keyboard with swipe capability.

Especially on a tablet, I find that no one keyboard does it all for me. In landscape mode I prefer the split layout in SwiftKey's 3 Tablet keyboard that is optimized for thumb typing.
