Let me make something clear, Intel having a majority stake or even a monopoly on high-end desktop CPU's will NOT make Intel CPU's cost a bazillion dollars as everyone is implying. Let me explain why.
By having a Monopoly in something like Oil or Power, you have a commodity that people will always need, and in regular intervals. That means if you increase the price, they probably are required to continue paying that increased price, and since Oil and Power are consumable goods, you need to keep paying for the same thing. Since the company controls the entirety of supply will always exist, they control the entire market and the price causing the consumer to lose out.
CPU's are NOT NOT NOT the same. Intel cannot force you to buy a new CPU every 6 months, they have to entice you to, or the demand needs to be there. People are claiming a monopoly will mean Intel can keep selling the same product for very high prices, but that's just not true. People will need more performance, and if they can't get it from a "newer" CPU, then they have no reason to buy it unless their current CPU dies, but in that scenario they would have to get a new CPU regardless.
There's also the fact that AMD will continue to offer better products, so if Intel continued to sell the same exact product for a high price, eventually AMD's mid-level products for substantially cheaper would be equal to or close enough in performance to justify buying them. Then there's the part where if Intel doesn't offer better products continually, nobody would have a reason to upgrade their computers\CPU's, and Intel's revenue would tank.
All of this talk of Intel having a "monopoly" (still not sure it really constitutes one) on the High-End Desktop CPU market causing huge increases in Price and Innovation is absolutely ridiculous.
