Well I did say "it appear" (meant to type appears...). So you can't really say it is false that it does not appear to me to be a unibody!
I still disagree. Without a tear down I just do not think you can be so 100% positive. What I agree with you on I have bolded above. The essense of a unibody is that there is a structural frame. So that being said I also disagree with you that it must have some
exterior aluminum to be a unibody. That is absolutely false. Technically it does not even have to be one continuous piece. Sure that's nice and makes for a better product, but it is also something you are just making up for your own little personal definition.
You may know this but some won't: The term unibody comes from the automotive world. It contrasts the modern construction of most cars bodies in that the body and frame are integrated as one cosmetic and structural component. It is never a single continuous piece - it is welded, riveted, bolted, etc. Old school cars had frames and bodies totally separate and thus they were not unibodies.
The alumimum we can see in images and videos for the TB looks like it might be nothing more than a cosmetic cover. From a tear down you could discern whether or not this aluminum is is fact structural as opposed to cosmetic. This is what I hoped to see more of with the battery cover off.
Look, I am
not saying IT IS NOT UNIBODY. I just marvel at your certainty without a tear down. I think it is also fairly clear it is not quite a unibody in the sense of the HTC Legend. That sucker is a unibody for sure. See pic below.
