BlackBerry 10 is the first version of RIM’s smartphone platform designed for touch devices. Previous versions, such as BlackBerry 7, were optimized for non-touch handsets with physical keyboards.
Other nice additions to it includes an adaptive software keyboard that adjusts to your typing style over time and a predictive word suggestion feature that can add words to your messages with a quick gesture. There is also a new camera that offers features such as composite photos that snap several images in quick succession so you can merge them into one idealized photo.
It also has new enterprise features including Balance, which creates two "personas" on a BlackBerry device, one for work and one for personal use.
