It's surprising what salesmen try to get you to buy. Years ago, when dialup was the norm, I was buying a fastest then available 28.8K modem. The salesman told me that I wouldn't get the full speed unless I also bought their premium phone cord to use with it. I asked him if he really thought that 6 feet of premium wire at the end of 2 plus miles of telco wire would make any difference. He had no answer to that.
Needless to say, I didn't buy the premium cord. But I wonder how many people did.
