Would you ever be able to justify using a 50mbps download speed connection? You would be able to download 24 hours worth of music in about 8 minutes at that speed. That’s amazing. Is it really necessary though? What’s too-fast?
There’s some good discussion and a good post about this topic up at Om Malik’s web site. Most of the comments fall around the topic of upload speed. Saying that the sensation of a fast connection is limited by your upload speed. I agree.
