AMD vs. Intel Brand Comparison (Score 1, Offtopic)

I'm not that familiar with AMD - or chips for that matter. However, I'm a huge fan of Paul Graham and his brand of philosophy that glamorizes open source technologies.

I know Slashdot attracts individuals that are very fanatical about open source technology. I'm curious to hear what the open source community thinks of AMD as a company and Intel as a company, and consequently, the culture of each and what brand do they feel like to be the most moral.

What I'm looking for is a heady discussion about the two companies with a focus on the both AMD's and Intel's brand. What makes either company appealing for you? How do they stack up against each other, whose got an advantage and why? Most of all, I want to hear some quality rhetoric in support of either company. Let's see some ill technology prose.

I am so far abstracted from the hardware industry that I would like people more familiar with it to help me sort out the 2 main chip brands and how I should view them.
