It's not insanity, it just depends what they were talking about. Personally I like the feel of the keyboard and find it's quite nice to type on, but I don't like the reliability issues. I've already had mine replaced once, and there's nothing preventing the replacement from failing again at some point.

It's very easy to brush aside the failure rate until it happens to you.

Well, mileage may vary and all that but my keyboard has a 0% failure rate so far. Knocks on wood.

Don’t do that... it’ll knock wood particles into the air, which might settle in the butterfly mechanism and jam up a key.
