Why didn't I file a patent years ago?

I can only blame myself on this one. I had the exact idea of a mobile phone design as this Irish guy.

With my old Nokia 3210, that had thin keypad side and thick screen side, it was more natural in my hand the other way around. My palms gave support to the whole phone, and the screen was not hanging in the air.

Also, this way your hands are protecting the screen. If you text or read text messages in a train, the guy sitting next to you can't see the screen.

Why, oh, why didn't I patent this idea back then? Stupid, stupid, stupid.
