Under U.S. Law, a company holding a monopoly who uses its position to "suppress competition" may be liable to penalties under the Sherman Anti-trust Act. In my mind there is no question that Apple is attempting to suppress competition here, and that it is using its economic position to do so. The end question then becomes, "Does Apple fit the definition of a monopoly?" In view of its market share, the answer has to be "no."* Still, they don't look very good here, do they?
*Is the answer the same if we look at revenues?
You forgot the part about Apple taking a stand (quite likely legal) against rip-off artists, counsellor. ASUS in this case is no "ordinary" competition. They are another legal target, and for now, Pegatron is enabling ASUS' activities. This is a prelude to a wider campaign by Apple against MBA knock-off artists. Same as Apple's moves against Samsung were the opening salvo of their wider campaign against Google (as we're seeing now with Apple's move against the Galaxy Nexus running stock Android.)
What, you assume Apple had no legal basis for doing this and just went into it blind??
