2008 has been the year of open source causing serious impact in the mobile industry but I could not imagine Symbian getting open sourced and that is exactly what Nokia has announced to do after acquiring Symbian. This has very long term implications for the mobile industry. One can expect to see business model innovation happening in this industry that has been bereft of innovation for more than a decade. Now this is is why I think now is the best time to be in this Industry. (Business model innovations are the most scarce form of innovation and is one of the toughest to make happen).
As always the best commentary about this development in the mobile industry is available at VisionMobile.
