Re: Unused speed
If you only ever use your WiFi for Internet access, you might be right.
For the rest of us, the extra bandwidth is essential.
There are two kinds of commentards: those who think there are only two kinds of commentards, and those who know better.
I use my WiFi for local comms between my machines frequently, but they're rarely bandwidth-limited. I'm not streaming HD video (or any other media), but that's my point - there are other uses for networking. So no, it is not "essential" for all of "the rest of us".
