With Andromeda potentially following Chrome OS's model for its
boot image rather than Android's, we may see Google attempt to leverage the existing Chrome OS infrastructure to make Android installations more modular, especially if the leaks that Andromeda will eventually be able to be installed on virtually any future x86, MIPS, or ARM device are true (which would tie in well with Google and Sony's recent work to
provide enhanced theming support, which OEMs can use to apply their customizations).
