I upvoted the comment because, for all Wired is jizzing over it, we're talking about a product that was just released. There're no really interesting information here. And from what I see of the product, it looks painfully limited. Perhaps it executes well, but it's just not doing much. Compare to Apple, which makes products that do a lot and still manage to do it well.
So when Wired mentions how it's just like the iPhone zomg!!!, I get this little voice in my head telling me the author doesn't know what he's talking about. That makes me more willing to upvote somebody making a snide comment that I agree with.
Maybe it's not the most intelligent HN comment, but how's that become groupthink to upvote it? How's it stupid or worth your losing your mojo?
