I can't help but thinking the thought of immortality is intriguing. But, to be human,is to be a part of a cycle. That age old cycle concludes with death, and the evolution of your genetics embodied in your offspring.
This would in essence put a stop to that cycle, and therefore evolution.
Also, there are many "human" things that machines have not yet been able to emulate.
So, although, it may be technologically possible for the avatar to become a repository for your "information", I can't see how it could actually be the "conscious" you.
