The obvious difference between typing on the BlackBerry Z10 and the BlackBerry Q10 is the physical keyboard. While the Z10 has various options for word prediction that can help out when typing on the virtual keyboard, the Q10 only has one option that may or may not be helpful when typing.
For the most part we've found it actually slows you down when using the word prediction on the Q10 as your fingers have to leave the physical keyboard area to jump to the predicted words and tap. However, some users may still find it helpful to use this feature.
The Z10 gives you various options for predicted words (over letter, in column) but on the Q10 its basically all or nothing.
Now as you type you'll see three suggested words over the keyboard. Simply tap any word to choose it.
Again - this may or may not be helpful given the physical keyboard of the Q10, but it's still great to have the option.
Are you a Q10 user? If so, do you use word prediction? Let us know in the comments!
