I suspect the answer is "tech press don't know pen cameras exist, because they were invented more than five years ago".

Further, even hidden cameras require a degree of boldness to point and position. It's far easier and less conspicuous to record when you simply need to look in the right direction.
Just as 20 years ago appearing that you were talking to yourself would have been odd, now talking out loud is normal because people have internalized that speaking into a phone's wireless mic is normal.
A pen camera, while useful as a sousveillance tool, isn't just as useful as a google glass.
Maybe I'm biased, but I don't see a "spy toy" being the same thing as a camera mounted on your head that could potentially film everything you see and directly upload it to youtube.
