I built a new system from the junk box for my workshop to hook up my new golf swing monitor to. To move 50GB of music out there I could have driven to the store to buy a wifi card, driven home, installed it and transfered the files at something like 40-50Mbps. Yawn. Or dump them onto my USB hard drive and schlepp them out there. Guess which I chose. (I had no other reason to do a network connection.)

Pick me! Pick me!!!

Actually, I would settle for a full duplex T1. xDSL sucks if you want to send anything big. Why haven't they implemented the adaption techniques that were developed for high-speed analogue modems in the 80's. They are asymmetrical but they load-sense and switch the fat pipe to the direction with the traffic. No reason xDSL couldn't do exactly the same thing. 

It flat pisses me off that the mavens of digital, to this day, refuse to believe there's anything to be learned from the analogue world.
