I suppose it actually makes sense in a screwed up way. Rather than selling a laptop with X processor and a laptop with X Y processor. They can instead simply sell the laptop with X and let people unlock to X Y. You were always buying a processor capable of X Y when you bought an X laptop, you just could never enable the Y. Depending on how they charge for this it may lead to cheaper performance laptops as they tend to whack on quite a large manufacturer margin as you go up the range.
Tease.
