I'm not sure about the "most advanced" title, but I plan on buying a black one at the end of the month.
Considering the way the silicon is set up in that phone, I'd have to agree with him. Up to this point, besides the Droids with the same system, there has never been a phone with this type of sophistication at the silicon level. It really is quite advanced. The level of engineering that went into the phone is what I found to be most impressive. Instead of throwing all tasks at a behemoth soc, you take a totally different approach and have multiple chips that handle specially assigned tasks. It allows for high level performance with chips that will consume less power. It really is a brilliant concept.
