Does 32X count or Sony PocketStation?

I would say yes, they were standalone products (even if you could include a 32X module on genesis right?)

I'm not aware of a standalone 32x.  Afaik, the only way it existed was as an add-on for the Genesis/Megadrive.  Is my recollection wrong?  Maybe I should Google it....
