I always ask my clients why they think they needed to sign up for the 2 gig or even the 1 gig service from their ISP. They have no answer other than that is what they were told was the best from the ISP. Well duh. Then I have to explain to them, even though they do not understand, why they do not benefit from anything over 100Mb/s, when all they do is watch Netflix, listen to Pandora, and shop on Amazon.
99.9% of customers do not need a 1gig internet connection, let alone 5 or 10. But these ISPs are pushing it like its the best thing in the world. Now if I could sell a $50k Kaleidescape movie server and my clients needed to be able to download a 100GB movie in less than 5 minutes, maybe. Or if they worked remotely for Pixar or something, they could utilize the speed. But in that case, they would hopefully already understand all the lingo and specs, and I would not have to explain anything.
It's not worth the effort trying to apease the client who wants the speed test on their phone to match the wording on their internet bill. :)
