If Google ported it properly it would be. 'Better' is ambiguous but I think for all but the Linux hardcore, Android is a better user experience at the moment.
SE are manging quite well (X10 anyone?). At the moment they're mainly WinMO based. The OS runs, it's just a matter of drivers and optimisation. These big companies have the capacity to do this with ease.
Community hacks/ports of Andriod or Maemo 6 are not the answer.
