AMD : Because you won't have to buy a new heatsink!
Fact is, AMD just doesn't have the balls to do what Apple did: advertise their inferior product as being superior to what "everyone else uses".
"The next time you settle on a CPU purchase, settle for AMD!"
Apple: Think Different
This is from the company that can't even figure out how to make a mouse with a scroll wheel. Worked pretty well for them. Their computers provided them with a couple of tangible advantages and they rolled with it, always advertising photoshop performance and obscure aspects of CPU architecture.
AMDs problem is that their operation is basically amateur hour, and they suck, horribly, at executing.
"AMD : Never living up to your expectations"
Apple sets the bar low, exceeds it, and they do it very very well. AMD needs some killer apps for Fusion, not this half assed Badaboom stuff. AMD should have released Llano before Sandy Bridge came out. THey should have had Quicksnyc first, but they didn't. Now they have a couple of "fusion" chips that are basically worthless other than for playing Quake 3. Advertising can only get you so far, marketing is about having a message that works with your product releases. All AMD has is some CG girls and obsolete roadmaps. There is no coherent message whatsoever, and they don't really have anything to sell other than cheap, "good enough", CPUs.
