So the primary reason I don't support that statement is that she can take her keypads off along with the fact that she eats food and drinks juice as shown in many videos on youtube and elsewhere. sorry if Im being literal.

MikufanMike that is true but also Hatsune Miku can do live concerts as a Hologram don't forget about that. Plus i guess Hatsune Miku could be an Android. But than again she could be a normal girl that's a Vocaloid.

There is evidence for both choices, but I believe there is more for her being an android.

Thats the magic of CGI. As a virtual popstar she is projected onto a transparent screen to perform. I saw her live in the city in october for mikuexpo2014. She was awesome and it really does look like shes standing before you. Theres some videos of it on my youtube channel. I swear my camera had a better view than I did. Search Google for KC2PIZ Miku and it should come up.

The other thing I forgot to add before is that a true android does not have feelings and lacks emotions. Time and again Miku has been shown as having them. Maybe Im being too literal tho.
