Research In Motion’s annual BlackBerry World conference kicks off Tuesday morning and new president and chief executive officer Thorsten Heins will take the stage to greet the thousands of show goers in attendance. Heins’s company has a daunting mountain to climb as its struggles continue, and this year’s show may be RIM’s most important to date as it looks to attract enough interest from developers and users to tide it over until its next-generation smartphone platform launches. RIM’s first BlackBerry 10-powered smartphone likely won’t be released until some time in October, but developers will get their first taste of a smartphone running PlayBook OS, the basis for BlackBerry 10, when RIM hands out thousands of prototype smartphones at the BlackBerry Jam conference that will run alongside BlackBerry World in Orlando, Florida. Will RIM make enough of a splash to instill faith in developers, users and investors that it can successfully re-enter a market not just dominated by, but completely owned by Apple and Samsung?
