In its most recent financial results, RIM revealed that it had lost $518 million, and that revenue had also dropped by a third to $2.8 billion. The company struggled to shift its PlayBook tablet as well, with just 260,000 shipping out. RIM has defended its decision to delay BlackBerry 10, saying that while it was ready to go at its core, the operating system still needed fine tuning before it could be unleashed on customers. The CEO of RIM, Thorsten Heins, also dismissed the idea of the company adopting Android or Windows Phone, saying that there was still room in the market for an alternative OS. [ via MobileSyrup]
