Another possible about Android equipment (phone and tabletpc)

Another possible about Android equipment:
Maybe Android will be used for low-grade phone only, and be used for a few of tabletpc (cost at least US$155). Not for anyother tabletpc and set-top-box. In future, Android tabletpc all will not use original edition of Android operating system, and will lock the bootloader (will be hard to brush anyother firmware), and user will be hard to get "root".(This aspect of is same as Android phone.)
