–Naked objects require a grammar to decide which UI to display. Java uses the type declariations as a grammar declaration. Smalltalk doesn’t have type declarations for its ivars so it won’t work: objects cannot be ‘naked’ we need to add some sort of grammar declaration before such a UI can be synthesized.

–Self is not Morphic-esque, AFAIK it’s the other way around: Morphic was designed on and for Self and was later ported to Squeak. So Squeak has a Morphic-esque UI
–There _are_ self VMs for Windows/Linux86 but they are experimental, see http://www.gliebe.de/self/download.html
