I wouldn't mind getting my hands on one to see how it does type. Personally, I hate keyboards that have buttons that practically fall down when you look at them. I'm also not a fan of rubber membrane keyboards for typing. Yes, I prefer the old IBM Model M buckle spring keyboards. If I didn't have to have an natural ergonomic keyboard, I would use a Model M on every system. I have.
That is what I was thinking when I read that used mechanical springs. If this thing types like the Model M did, this is gonna be a good keyboard.
Perhaps the Engadget opinion needs to be validated up on by a [H] opinion.
