Time is quickly running out for BlackBerry. Network effect is deeply at play in the smartphone market, to the disadvantage of BlackBerry [irrespective of how good BB10 OS itself is]. One opportunity, however, that is ripe for exploitation is the still-evolving market for "smart TVs", the ones that increasingly resemble computers and smartphones, yet remain essentially TVs.
No software platform or manufacturer is a leader in this still-emerging space. BB should act fast and partner with a solid TV-maker to launch a range of BB10-powered smart TVs. The lack of applications for BB10 OS doesn't hurt BB in this market [at least not yet]. BB10 is a solid OS and its spread into the smart TVs market will bring benefits to BB10 on smartphones as well [increased developer awareness, increased application development, increased consumer familiarity with BB10, etc.].
