Arth Anderson got a bad rep after Enron, no bid deal there. If they feel like a chump they should but not because AMD dropped them.
Duron used the same socket at Athlon so there is not problem there. Those duron supporters can still get cheap Athlon XPs for the price duron used to be so I doubt they feal slighted and if they did that URL is for an article from spring 2002 so they've had plenty of time to get over it.
The 300 amd employees article is from 1999. Why do you feel the need to dig up 4 year old articles to discuss people feeling like a chump.
The whole chump vs bonefish attitude seems very childish to me.
