Research In Motion got to set the news agenda yesterday with a big reveal of its upcoming BlackBerry 10 software. With a plummeting market share of smartphone sales, it’s RIM’s last roll of the dice to stay relevant in a world of iOS, Android and (possibly) Windows Phone. The new software has met with generally positive reactions from tech blogs, but RIM also talked about the importance of music, films and TV shows. All three content categories will soon be added to its BlackBerry App World store, although RIM didn’t talk about licensing or tech partners – for example, whether longtime partner 7digital is involved. For all the bad publicity around its market share, BlackBerry still has 80m subscribers. The question is how many of them will buy music, versus simply using email and BBM.
