Taking shots at Nokia’s ailing smartphone platform Symbian is almost too easy these days, and it would seem another hardware manufacturer is announcing that it wants off the bandwagon in favor of Android. Sony Ericsson has been developing Android based phones for quite some time now, but many were wondering just how much longer they would continue to support more than one mobile OS, and now we know. “We have no plans for the time being to develop any new products to the Symbian Foundation standard or operating system,” Aldo Liguori, a spokesman for the London-based company, said by telephone today. Liguori confirmed remarks made by Chief Technology Officer Jan Uddenfeldt to Swedish technology newspaper Ny Teknik.

Symbian continues to hold onto a tenuous lead in the smartphone market, but its share has declined from 51 percent to just over 41 percent over a one year period. With the loss of Sony and Samsung the Symbian Foundation’s only high profile partner is Nokia who for one reason or another continues to use the OS to power its high end smartphones. To be fair Sony hasn’t formally withdrawn from the Symbian Foundation, but with no new products being planned it sounds more likely this will evolve into a common law divorce, a separation without all the messy paperwork.

Symbian keeps falling into the same category as RIM, powerful but faltering. What would it take for these guys to get back in the game? Let us know what you think after the jump.
