Wow; that's a fun idea to toy with! But... Unless it's made of flesh, bone and blood, I'm not really interested... It's a trust thing, for me.
Another question would be: How would you pilot a body like that? Remote control? Personality copy/paste? Brain replacement surgery? If the latter, I might still be interested. If not, then it would, to me, simply be fake..

It's a philosophical question: Once you copy yourself, and put the program into another device, then the new you will have all the data of the old you, but the old you would still be the you that you experience from. To kill off that old you would be the best option for the new you, but then, you'd be dead, and the effect would just be reproduction, not change.
Of course; if you'd simply transfer your brain tissue, or at least the bits of it that make you you, to the new body, then I don't see a problem with it...
That, and please; make it flesh and blood. It's good material; long-lasting, self-repairing... Whereas even with nanobots, if it breaks, you're in trouble. A program might break down, and the self-reparation would simply stop.
Also: Where does this body get the materials for energy and self-repair? Nutrients are biology's answer to that, and it's just a brilliant system.
For me, it's not about the looks of the thing, but about the materials used. (The looks are what make me want it; the materials are what makes me reject the idea.)
Sorry; I just... Can't put my trust in technology like that. Bio-engineering, though.. That's something else.
