After a slightly awkward start in the UK this morning, Research In Motion has launched its new BlackBerry 10 platform along with the first two compatible devices.

The BlackBerry Z10 is entirely touchscreen, while the BlackBerry Q10 combines a touchscreen with a traditional physical keyboard. Both run 1.5GHz dual-core processors and have 2GB of RAM plus 16GB of expandable storage.
