I assume that "delidding" is fairly new, however, clearly people wouldn't feel that they had to delid if Intel just packaged their product better. If they set up their processors with better TIM, nobody would have to delid. It seems strange to me that Intel would continue to put out products which are easily modified (voiding their warranty in the process), and able to get such great results. Especially, considering their "k" processors are released unclocked with the intention that their owners can overclock, however, some thermal restrictions with Intel's current set up make it difficult to do sometimes without a delid.
It clearly wouldn't be that expensive for Intel to fix the problem. Have they ever made a statement on people delidding and do they have any intention of fixing the problem so people won't have to? What is their stance? I think the fact that people are delidding makes Intel look bad, and I would think that they would rather not have that reputation.
