IBM Simon (en.wikipedia.org)

Turns out Simon lost due to poor memory. ;)

Interesting, I hadn't heard about that. I was expecting to see a corporate version of http://en.wikipedia.org/wiki/Simon_%28game%29

Had one. Brilliant software. Horrible battery life. Analog cellular meant glacially slow internet access. I loved it and hated it people looked at me like I was from mars (might not have been the phone). It was the Google Glass of its time in some ways. Went right from the Simon to the Palm Treo.
