Nokia is apparently not amused that Apple’s nano-SIM has been chosen as the future standard:
Nokia continues to believe that the selected nano-SIM proposal is technically inferior and not suitable for a number of applications, but the ETSI Smart Card Platform Technical Committee has now made its decision. Nokia believes that the existing micro-SIM (3FF) will continue to be a preferred option for many manufacturers and devices and so ultimately the market will decide whether 4FF is widely adopted.
I am sure the market will decide. But this is not 1999 when Nokia ruled the roost. I believe the market will follow Apple’s lead.
