RDillus: That's a very misleading claim. Yes, you need an extra performance for emulation of an operating system on top of another OS. But figure "5 times stronger machine" is absurd - it might be few percent stronger, or many more times, depends on the both OS's, processor, etc. Secondly, "emulator" might be just wrapped API, by which I mean if you have a function call for some Symbian function, on Maemo it would just call some function, which would be internally different, but would behave in the same way as on Symbian. That way, you wouldn't need nearly any performance extra, because you are still running only one OS. This is, as far as I know, how Wine works...
