The World (still) Needs AMD
Like Bruce said, we owe a lot to AMD. An Intel without AMD is a very scary scenario from a consumer value standpoint, but everyone (surely) knows this already. ARM is a fortunate counterpoint to the duopoly.
AMD doesn't need to compete with Intel, it's been good since the early 2000's at delivering measurable value purely by differentiating. Nintendo learned that early on with the Gamecube (using, then, ATi), MS and Sony have since figured it out. AMD need to market that message to the rest of the world to be successful.
My biggest complaint of AMD is similar to the first commentard's. I can't buy the AMD solution that I want!
(although I suspect it's more a case of shite motherboard makers lacking imagination in my case - I want small form factor AM3+ for steroidal linux virtualisation)
As for whether or not their processors are good for the average consumer, I think the reflex is to compare them to the older approach of making a PC where the thing is large, noisy and has to have a discreet video card and mechanical disk - that is not what new consumer PC deployments look like. They want small, they want quiet, they want 3D and they want it to playback their pirated TV and movie files without skipping or distorting. This is AMDs exact strength with their APU line of processors, there's no technical reason they can't profit on those use cases.
And I like AMD's new C-level guys. Having Papermaster (Apple's doomed antenna-gate patsy) and Read (who doesn't like an ex-IBMer?) driving the direction of the company sounds like a really good start. Any time I read an interview with either man they just reek good sense. Hopefully this important computing company survives well past the post-PC era.
*in full disclosure: there is not a single AMD processor active in my house at the moment (I'm ignoring my Geode powered firewall). I'm not a fanboy. I just respect that they seem to make some really good shit - Sony/Nintendo/MS seem to agree
