As technology evolves the tangible benefits of having double or tripple the performance of a console starts losing in the war of diminishing returns. Furthermore computers are pretty wasteful of the performance they have and you have to expend a lot of resources simply rendering at a high resolution due to the gaming environment computers are in with high resolution monitors sitting very close to the user.
As for the percieved attitude its probably fear. I know of far more hardcore gamers who have given up PC gaming than have joined the ranks and those who I do know only play WoW. Given that my impression is repeated here and even on technology focused sites such as www.beyond3d.com it doesn't paint a very good picture.
Tease.
