how about global market share?
2008: 52.4% of smartphones (RIM 17%, Apple 10%) [1]
2009: 47.2% of smartphones (RIM 21%, Apple 15%) [1]
Android came in at 0.5% and 5% for those two years.
Gartner forecasts that Symbian will remain in the number one smartphone OS position until 2014 when it is contested by Android [2]
Sure, it's in decline now, but it's been a phenomenal success.
Symbian OS has several version. The version that ships in volume powers devices like Nokia C1-01 http://store.nokia.com/webapp/wcs/stores/servlet/productdeta... or worse. It's not the same product as iPhone or Android or even the old Palm OS shipped on Treo.
The share of Symbian OS devices shipping a version comparable to iPhone or Android is a blip on the radar. A drop in the ocean. And a peasant among Kings.
Most of Nokia's cheap phones are on the Series 40 platform, which is a closed "non-smart" OS (that has nevertheless grown some fairly smart features recently, like QWERTY keyboards and a HTML browser).
Symbian by Nokia comes in three flavours:
- Symbian^3, the latest and greatest -- e.g. the E7: http://www.forum.nokia.com/Devices/Device_specifications/E7-...
- Symbian^1, the previous touchscreen Symbian version (a.k.a. S60 5th Edition): http://www.forum.nokia.com/Devices/Device_specifications/C5-...
- Symbian S60 3rd Edition, still used on keyboard devices: http://www.forum.nokia.com/Devices/Device_specifications/E72
sign of the first derivative.
The sign of the first derivative only gives you the present rate of adoption/abandonment of the platform, while integrating gives you a measure of success over the platform's entire existence.
Pretty much since the time it was called EPOC. It failed to grow and support more resources, as phones became more powerful than the desktop computers of the time it was designed in, and it's no longer suited for current smartphones. It still excels on the low end, where neither Android nor WP7 reach.
As a platform, surely not. The wheels came off by the end of 2008 when S60 5th Edition went touch-only, leaving keyboard devices still shipping with the hopelessly outdated 3rd Edition. Symbian touch devices never gained any platform traction.
Was it a success as a software foundation upon which handset makers could innovate, as had been the original idea behind Symbian? No. Everyone that used Symbian abandoned it for more flexible alternatives. The lack of a unified UI development track didn't lead to the hoped innovation, but merely fragmentation that ultimately doomed Symbian. (It didn't help that the most popular UI layer, Nokia's S60, was so poorly designed and thoroughly mismanaged.)
I actually use a Symbian^3 device, the Nokia N8. It's not bad at all. I love the physical design, and the software works fine for what I do (although the browser is a turd, it's replaceable by the fine Opera).
Still, I can't escape the feeling that this is the OS that Nokia should have had over two years ago. Also, it's a development dead end. Symbian^4 was supposed to be a UI rewrite, but it failed. The promised improvements to S^3 have been slow in coming. (Still no Qt 4.7...!)
How is Symbian a success at this point? What reason would Elop -- or anyone else -- have to believe that the existing software development structure at Nokia could substantially improve this situation?
