Canadians who have clung to their aging BlackBerrys finally have an upgrade. The company behind the once-dominant smartphone debuts its new touchscreen device, the BlackBerry Z10, today in stores across the country. The move comes after several delays left some longtime BlackBerry fans sticking with their older phones or switching to a competitor's phone. Some analysts have been concerned that BlackBerry's launch came too late to recover the lustre of its name. But anecdotes from the UK, where the phone launched last week, suggest the new BlackBerry is selling at a steady pace. Fans of the phone's physical keyboard will have to wait awhile longer though _ the new keypad version of the device won't launch until sometime in April.
