Well I am a person who enjoys playing Agricola, so screwing around with fiddely bits is more up my alley.Every group I played with, and I played with several since coordinated or helped coordinate a couple of game days in a major metro area, had the same experience.
I'm happy for you if you were so freakin' brilliant that 4E combat ran fast. But that makes everyone I gamed with (over 2 dozen) idiots who "couldn't grasp the concepts". Give me a break.
Conversly, I share your feelings in regards to fighting videos/MOBAs/Starcraft. Inputing around 150 commands per minutes for 30(ish) minutes intervals while also considering economic and strategic problems?? Sounds hard.
When it comes to D&D, I don't blame people who want a fast easy game. That's more time to focus on characterization.
