While the Z10 can be seen as BlackBerry’s bid to attract new, hip users, the BlackBerry Q10 should supposedly appeal to old-school BB lovers who are ready to dump their Bolds and Curves for something better. Instead of a large, all-touch experience, the Q10′s screen is small and half of the phone is dominated by a keyboard. It runs the Canadian tech company’s latest and greatest OS: BlackBerry 10.1. The question is whether the interface that runs so well on a larger, touch-only device will also work on a half display, half keyboard phone? The answer depends on whether you’re willing to dive deep into the Q10′s many layers of functionality and keyboard secrets.
