In practical terms though, where do higher download speeds stop being an advantage?
You are after all dependent on the bandwidth of the remote server, Photobucket, YACF, ITunes or whatever.
A high bandwidth in the office may allow 100 people to each grab a slice of a 100Meg connection but you may still be downloading from a server with a 10Meg connection.
Having never tried downloading, say, a 10MB podcast using >100Mb connection, is it really 10x quicker than a 10Mb connection?
I'm surprised to see a Web development company with such poor bandwidth, I'd have thought that sort of performance could have an adverse effect on your business.
I cancelled my free trial of 20Mb (18Mb donwload speed) and reverted to my 10Mb because I couldn't see any significant difference.
