Yes there's pretty good evidence that the physical structure of the brain is sufficient for long-term memories. ... If human personalities were stored as dynamic processes, that would be a strong argument against cryonics, however this is unlikely to be the case; if they were, we would expect that hypothermia causes amnesia.
I was under the impression that hypothermia is not the same as cryonic freezing, and that even when a person is undergoing hypothermia, he still has brain activity. I am reasonably sure that the person is at least undergoing metabolic activity, because otherwise, in the absence of cryoprotectants, his cells would freeze and burst. I could be wrong about this, though.
As far as tissue damage is concerned, AFAIK our current technology is not advanced enough to even preserve human hearts, livers, and other organs (for the purposes of transplanting them into other patients). That is, we can freeze an organ, and we can thaw it, but in the process it is damaged beyound repair -- and we're talking about relatively simple organs here, not brains. As I understand it, the damage is caused by the following factors:
You say that this damage is not a "deal-killer", but if this were the case, we could at least cryopreserve individual organs today (not to mention whole mammals). Cryonics advocates usually agree with me here, but postulate some form of future technology which will be able to repair this damage. I'm not sure what kind of technology could do that, though. Molecular nanotechnology is the most popular candidate, but I am not convinced that it could, in fact, exist (which is one of the reasons I'm not too enthusiastic about the Singularity, as well).
I'm not sure what you mean by this, though:
Note that unlike antiaging treatments, you can get immediate results
What do you mean by "immediate results" ? Cryonics is kind of the opposite of "immediate", by definition.

Yes there is some metabolic activity in hypothermia patients. However, metabolic activity isn't the reason for no ice crystal formation in hypothermia patients. The relatively high temperatu...
