I didn't realize the discussion was heated at all.:-[ I'm not in the least bit upset. I'm just deciding between multiple devices and want to know as much as I can. Just saying the Thunderbolt has aluminum on the interior of the device does not make it so, although I hope it does.
Also, just because there is not(for the sake of argument) aluminum on the INSIDE of the Thunderbolt, DOES NOT mean HTC skimped in any way shape or form!
Up to this point, as far as I am aware, the aluminum unibody design of HTC devices has NEVER included anything but the outside frame of the device. I have a Nexus One in which this is the case...and HTC sure did not skimp on this device construction, I can tell you that. Just because HTC may use plastic, magnesium or several other materials on the interior of a device does not in any way take away from the aluminum unibody exterior.
Again, I'm just trying to learn as much as I can about this device. I'm willing to challenge assumptions though to try and get facts, not speculation. Like I've said several times: I WANT there to be as much aluminum as possible. I PREFER overbuilt, well constructed devices. If not, I might have an Atrix, but the all plastic construction turns me off...big time. It's also a big reason why I have a Xoom...because of it's aluminum exterior. Although, it does have a strip of plastic on the top that I am not fond of.. but this does not turn me off enough to have not purchased. Just like if the Thunderbolt does not have interior aluminum it will not turn me off the device.

I just want to know if it does...FOR SURE


That said I do wish/hope the battery cover is aluminum. Or maybe if I get the HTC extended battery, HTC will make an aluminum cover for it. That would be brutal and I would be willing to pay more for it. Though I don't know how this would affect reception.
