Research In Motion's long-awaited BlackBerry 10 operating system launched this week with impressive fanfare -- and a boatload of solid-to-glowing reviews from tech pundits looking at the new BlackBerry 10 devices, the Z10 and the Q10. It also marked a rebranding; RIM now has the same name, BlackBerry, as its flagship product.
Now comes the hard part. If BB10 marks the start of a BlackBerry turnaround, all the better for smartphone competition. If it's BlackBerry's last gasp, at least the once-proud company went down fighting.
