^^ Well I intended this thread to be about the advantages and disadvantages of fragmentation wrt Andrioid vs iOS since that has been a topic that I had seen quite a number of debates about.
Since people have brought Symbian OS into the picture, then let me tell you, I still think Symbian is technically superior and has a lot of potential for Nokia or any other company if they decide to make use of it. And yeah I agree with you that "technically superior" doesn't always mean market acceptance and vice versa, a technically inferior product can be made to sell. Apple wouldn't have been able to sell a product after 1997 if that had not been the case. Yeah I also agree that symbian did not see a proper refresh for a long time, but the the fact remains that it had the majority of the market and still does with 50% market share. 7 out of 10 smart phones sold in India are symbian based and made by Nokia. Although the relative market share has decreased with new platforms entering the scene, the volume of sales for symbian devices is still on the raise indicating that people are still buying into this platform. Android and iOS require costly hardware to be properly usable. Symbian hardware can go as low as $100 and still remain usable for the lower end of the smart phone market. Even on the mid/high end, phones like N8, it brings new stuff for a mobile platform like USB Hosting. Nokia makes great phones, however they don't know how to market and that had been the bane of Symbian as well. Had Symbian been acquired by Apple instead, everyone would be singing praises of the platform. It has everything essential unlike Android and iOS which are still not mature enough and have bits and pieces missing. In any case, Symbian 3 is open source OS now, so lets see where it goes. I don't see symbian going down anytime soon. Not unless Phone manufacturers want to kill it. As long as there symbian phones there would be people to buy them.
hyeah:
