You're forgetting about portable (notebook, tablet, etc.), where most personal computers are sold.
One reason I even consider buying a desktop anymore is that discrete-GPU notebooks tend to be enormous and/or awful. If AMD can produce an APU with reasonable graphics performance, I'll gladly buy a notebook with that in it rather than a new desktop rig.
