My point was simply that you attempted to craft a rebuttal that was an obvious, direct contradiction to your immediately previous statement. Now, however, you are trying to explain that lapse by claiming that you "can't be bothered to argue any more with people who don't understand the basic technologies at the core of the debate."
Just reread the complete dialog and you should understand what I mean. In such a case, I think you've pretty much just shown the true tenor of your arguments.
We do seem to agree, however, that in the majority of cases for streaming video services the practical differences between a 100Mbps ethernet connection and a potentially (but perhaps not always) faster WiFi link between your internet service provider and the Apple TV are pretty much nonexistent (that is, it makes practically no difference).
