My question is, at what point does the constant immediate response times, flashy images, background audio / video, never ending advertising, and ultimate, absolute freedom to go wherever the Web could possibly offer, no matter how badly or lazily coded, become... tiring?
Freedom to go wherever I want and sheer speed are never tiring IMO, quite the opposite. And if blocking all the bad stuff makes the experience that much better on less powerful systems, what's it gonna do on more powerful ones?
