I wonder. I'd argue that watching an unboxing gives me a much quicker idea of what's really going on than trying to tease out what's the truth from the reviews. ("20 positive reviews. How many are fakes? Let me read the 3 stars, maybe they're better. I'll read the 1 stars and try to assign weight).

Maybe I'm just picky but I find reading/judging Amazon reviews a pain in the ass.

I don't think I can tell much of anything from an unboxing video. I have no idea why they are so popular.
