I'm considering something ultra-portable, and Korg's two offerings are in the mix.

I know the Liverpool has some exclusive Beatles styles in a protected memory area which can't be accessed or exported to other machines.

I've also read that you can load the styles from the MicroArranger, Pa50, Pa80, etc., into the Liverpool. Does the MicroArranger have any features or content that cannot be transferred to the Liverpool?

In short, for the same price why would anyone buy a MicroArranger instead? Thanks!
