Symbian applications are just like other OS' applicattins, these applications does not requires more power than other applications, that's not the point here, there are symbian applicatioons which dosent require any processor load.

What is necessary to run symbian applications on these phones is an Emulator, like someone said in another post, and this emulator is probable that it doesn't exists, at least I haven't heard about it.

if yu udont have an emulator, you can't run symbian appliccations on any otheer platform than a symbian phone

It's like making a human live on the water without Air, that AIR is the Emulator.
