When the young members of Generation-i use their phones to send text messages, the small keyboards make typing awkward and abbreviations even more important: "b4n" (bye for now), "cu" (see you).
I've had extensive hands-on time with the SwiftKey-like input scheme and, apart from its clean layout, I can't see much use in the keyboard's predictive text capabilities, nor can I envision prospective users investing in its idiosyncrasies.
